The Battle at Pluto
In the late 22nd century, an alien race known as the Gamilons have attacked the Earth, bombarding it with radioactive bombs and forcing the population underground. However, the radiation is seeping into the planet; unless it's removed, Earth will become uninhabitable in one year. War with the Gamilons has also destroyed the Earth's space forces except for two ships -- the Paladin, commanded by Alex Wildstar, and another ship, commanded by Captain Avatar. During a battle at Pluto, Avatar's ship is damaged. The Paladin gives Avatar's ship enough time to escape, but is destroyed in the process.
Meanwhile, a non-Gamilon alien ship is hit in the crossfire and crashes on Mars. Cadets Derek Wildstar, Alex's younger brother, and Mark Venture investigate and discover a beautiful, dead woman, ejected from the escape pod and clutching a message capsule. They return to Earth in Avatar's battleship, and Derek notices the absence of any other ships. On the way back, they learn of Alex's fate. After they return, Derek confronts Avatar about Alex, but Avatar says it was Alex's decision to remain.
When the message capsule is decoded, it contains a message from Queen Starsha of planet Iscandar. Starsha says the messenger was her sister, Astra, and offers Earth the Cosmo DNA, a device which can remove the radioactivity. The message also contains plans for an advanced-technology Wave Motion Engine -- capable of faster-than-light travel. As the Earth Defence Command deliberates, a Gamilon recon plane is detected sniffing around the ruins of the sunken WWII battleship, the Yamato. Out of sheer boredom, Wildstar and Venture take a plane out (unauthorised) to investigate. The Yamato appears to be nothing more than a hunk of ruins, however, leaving the cadets puzzled as to why Gamilon would be interested in it.
The Sea of Fire
Desslok, getting some satisfaction out of seeing his inferior officers fail at their attempt to stop the Star Force with space mines, now offers his own solution: a matter-eating Ecto Gas. Desslok plans to use the gas, and an electromagnetic force net, to chase the Star Force into the corona of a red giant star, Voltan -- The Sea of Fire. He is so confident of his new invention that he tells General Krypt not to bother reporting on the success, and strides off to his bedroom to dream of the conquest of other worlds.
The Gamilons begin their offensive by ensnaring the Argo in a powerful electromagnetic space net, and then sending a volley of missiles. Captain Avatar suffers a black-out, which he attributes to an earlier battle wound, and fails to order their interception. Wildstar initiates it instead, without the order, leading to a later reprimand. The ship barely manages to pull out of the space net and evade the Gamilon missiles. Dr. Sane knows the real reason for Avatar's collapse -- radiation poisoning. Privately, he urges Avatar to consider hospitalisation, a suggestion which Avatar adamantly rejects.
With the Star Force's flight path restricted by the space net, the Gamilons then loose Desslok's Ecto Gas upon the Star Force from behind, forcing them to flee toward the Red Star of Voltan. There is no choice but to fly dangerously close to the corona, and the ship and crew are on the verge of melting. But, the plan backfires when the ecto gas is drawn into the Sea of Fire, and the Star Force clears a safe path through the fire with a blast of the Wave Motion Gun.
On Gamilon, Desslok rebuffs his aide General Krypt's suggestion that they send out interceptors, and instead suggests sending congratulations. He muses to himself, "How could the Star Force have escaped? ...It was a perfect trap!"
Earth has 308 days left.
The Star Force encounters an unmanned Gamilon fortress floating in space, which moves toward them. Sandor takes a plane to investigate, but the magnetron waves the fortress is emitting shake it to pieces. Realizing this is what could also happen to the Argo, Sandor and Wildstar approach the fortress with a special plane unaffected by the waves. Once inside, Sandor tells Derek about his brother Alex. Sandor and Alex were good friends at the academy, and Sandor admits he felt responsible for Alex's death because he was in charge of maintaining Alex's ship. When a robot nearly surprises the two, Sandor says that as a child, he discovered the consequences of acting foolishly when he got into an accident on an amusement park ride. Meanwhile, the Argo, suffering damage from the magnetron waves, prepares for a space warp which will take it out of danger, but leave Sandor and Wildstar behind.
When Sandor and Wildstar reach the central computer, it injures Wildstar and captures Sandor. Sandor then tells Wildstar his arms and legs are bionic -- a result of the accident -- and can be removed. When they get to the entrance, Sandor says his bionic arms and legs are also bombs, but he can't trigger them any further than the entrance. Sandor orders Wildstar to get to a safe distance, then detonates the bombs, destroying the computer and stopping the magnetron waves. The Argo cancels the warp and Wildstar heads back to find Sandor.
On Balan, General Lysis clenches a Gamilon cigar in his mouth, which Vulgar is unable to light. He chides Vulgar for the uselessness of his lighter and his space fortress. Back on the Argo, Sandor, sporting new arms and legs, greets Wildstar. Derek says that Sandor's resilience gives him hope that Alex is still alive. Sandor says that if so, it will mean just as much to him as it does to Derek.
Earth has 260 days left.
While the Star Force is still on its way to planet Balan, Communications Officer Homer visits the Holography Room to view images of his home town, but has an emotional breakdown, declaring, "It's all a lie!" Shortly thereafter, the bridge crew sees Captain Avatar communicate with the Earth Defense Command. The Earth Defense Command says that conditions on Earth are tough, but that they are getting by. Once the transmission ends, however, Homer blurts out that they are all being deceived, saying that the Star Force has no idea where they are going. He then collapses and is whisked away to the infirmary. Venture says that Homer's actions may have been puzzling, but his concern is a valid one that is on everyone's minds. Captain Avatar replies that even though there is no guarantee of mission success, the Star Force is Earth's only hope of survival, and they owe it to Earth to believe in their mission.
On Balan, General Lysis muses on the effectiveness of the communications relay satellite which he has planted to enable the Star Force to talk to Earth. The plan is to weaken the Star Force by allowing bad news from Earth to destroy their morale. Back on the Argo, Wildstar discovers Homer secretly making a call to Earth, during which Homer learned his father was very sick. Upset and homesick, Homer bolts, finds a space suit, and jumps out an airlock intent on floating back to Earth. What he floats to is, instead, the Gamilon relay satellite. His depression and delusion melt away as he realizes the danger this presents. Before long, Wildstar, leading a search party, locates Homer and rescues him. Wildstar hands Homer the firing controls and lets him blow the satellite to bits.
Earth has 255 days left.
The Battle of the Rainbow Galaxy
The Star Force has arrived at the Rainbow Galaxy nebula. General Lysis's task force begins its attack by deploying fighter planes to lure the Star Force's Black Tiger squadron away from the Argo. The plan works, and once the squadron is away, the Gamilons launch precision bombers, and use SMITE to teleport them into close range of the Star Force. The attack cripples the Argo's radar. The Black Tigers are recalled, and drive off the bombers, but not before the Argo suffers significant damage. Not relenting, Lysis next sends torpedo planes, warping them to the opposite side of the Argo. They inflict severe damage to the ship before being driven off, and nearly all of the Argo's gun turrets are destroyed. The Black Tigers then return to the ship for refuelling.
Striking the final blow, Lysis teleports the Drill Missile bomber right in front of the Argo. The gigantic missile is dropped, and plows into the Wave Motion Gun, rendering the gun useless. The drill head penetrates into the gun's control room. With the Argo defenseless, the Gamilon fleet moves in close for the kill, and begins a close-range, ship-to-ship bombardment. The Argo's last remaining gun turret explodes, and the ship is utterly defenseless. But, Sandor and IQ-9 manage to break into the missile, and with 30 seconds to detonation, switch some wires and make it back itself out. The Drill Missile flies backward, right into the Gamilon fleet, striking the very battle carrier from whence it came. The debris from the exploding ship strikes the other three carriers, wiping them all out. Only Lysis's command ship remains. Stunned at this turn of events, Lysis attempts to ram the Argo, chasing the Star Force into the black gas cloud. With the Star Force unable to see his ship, Lysis maneuvers beneath the Argo and grapples onto the lower hull. He contacts the Star Force by video to inform them that the battle is now over -- he has placed a bomb against their hull. Captain Avatar tries to convince Lysis that the Star Force is no threat to Gamilon, but just wants complete its mission to Iscandar. For a moment, Lysis considers the matter, but he refuses to relent and starts the bomb timer. His ship ungrapples and moves away, but is heavily damaged in the ensuing explosion. As for the Argo, half of the underside is utterly destroyed, but still the lucky ship survives. Lysis's own ship is too damaged to continue the fight, and he returns to Gamilon in disgrace, knowing that unpleasantness awaits him.
After holding a burial at space for those lost during the battle, the Star Force pushes on toward Iscandar.
Earth has 214 days left.
Dragged to Gamilon
As the Star Force enters the Great Magellanic Cloud, the galaxy in which Iscandar resides, they receive a strong radio signal which affects all of the navigation instruments. It turns out to be a transmission from Queen Starsha herself. She congratulates the Star Force on its brave journey, and instructs them to follow her guide signal to Iscandar. But, once they enter visual range of Iscandar, the signal is cut off, and navigator Mark Venture makes an even more startling discovery. The video data indicates that there are two planets at Iscandar's location. Radar detects a group of missiles coming from Iscandar. The missiles detonate around the Argo, releasing a magnetic ferrite cloud which hovers around the ship. Analysis reveals that the missile fragments are of Gamilon origin. Wildstar then realises that one of the two planets must be Iscandar, but the other is Gamilon!
On Gamilon, Leader Desslok's treasure pool massage is interrupted by a call from Queen Starsha. She chides the Gamilon leader for his unprovoked attack on Earth, but he explains that the Gamilons need to find a new home, and that Earthlings are not a sufficiently civilised race to worry about preserving. A short time later, Desslok addresses the Gamilon senate. He explains the plight of Gamilon, a semi-hollow planet which is volcanically unstable, with seas poisoned with sulphuric acid from the lava. Gamilon can no longer support humanoid life, so a new home is needed -- Earth. Desslok's plan is to use a magnetic ray to drag the ferrite cloud, and the Star Force, to Gamilon, and into the sulphuric acid sea.
On the Argo, shock waves are felt as Gamilon's magnetic ray is put to use. As planned, the ship is dragged helplessly into the seas on Gamilon. When the Star Force realises the danger of the sea, they take off, but not before the acid manages to melt the third bridge strut. The entire third bridge falls off and into the sea! The Gamilons then begin dropping depth charges on the Star Force, trapping them above the deadly seas below.
Earth has 164 days left.
The Battle of Gamilon
Trapped between depth charge bombardment and the sulphuric acid seas of Gamilon, the Star Force desperately tries to find a way out. At his command centre, a building suspended from the ceiling of Gamilon's upper shelf, Leader Desslok monitors the battle's progress. He lashes out at General Krypt's offer to relax and have a drink. On the Argo, out of ideas, Wildstar seeks advice from Captain Avatar who suggests that they actually submerge the ship for 10 minutes in the acid sea, and seek out a volcano to disrupt using the Wave Motion Gun. After a few minor pieces of the ship have fallen off, IQ-9 spots the desired volcano. One hit from the Wave Motion Gun sends Gamilon into seismic upheaval. Desslok momentarily loses his sanity, exploding into a fit of uncontrollable hysteria.
The Star Force ascends from the Gamilon sea. Leader Desslok orders the ceiling missiles above the central Gamilon city to be dropped upon the Argo. His aide, General Krypt, wigs out at this suggestion, knowing that it will destroy the city as well, and begs Desslok to end the battle and seek a truce. This earns Krypt a snide comment from the Leader (though in the Japanese version, it's a shot in the chest). Missile fire rains down on the Star Force, and so Wildstar orders the Argo to fly directly above the central city in hopes of discouraging further attacks. But this does not dissuade the Gamilons, and ceiling missiles drop like stones, wrecking the city and causing further volcanic eruptions. Gamilon's tectonic structure becomes unstable, and huge sections of the upper shelf collapse and fall upon the cities below. A shot from the Argo'smain guns strikes Desslok's command centre, which plummets to the ground below. Desslok himself is covered in rubble, but falls through a trap door, his fate uncertain.
Gamilon falls still and silent. Wildstar finds Nova weeping on the main gun deck, and declares that he believes that this was their last battle. The Argo, badly damaged, lifts off. As Captain Avatar delivers a message of congratulations to the crew over the public address, planet Iscandar comes into view.
Earth has 161 days left.
After defeating the Gamilons, the Star Force lands at Iscandar, where Queen Starsha welcomes them. At first she mistakes Nova for Astra, her sister, but Wildstar says that Astra didn't survive her trip to Earth. He adds that Earth owes both Astra and Starsha a great debt for their help. As the Cosmo DNA is loaded onto the Argo, Starsha mentions that she has been taking care of a wounded Earthling who is now ready to travel, and she wants to send him back to Earth. The Earthling turns out to be Derek Wildstar's older brother Alex, and upon seeing his brother actually alive, Derek breaks down and embraces him.
Meanwhile, Assistant Engineer Sparks kidnaps Nova and leaves with several others to settle on Iscandar. Trouble is, the island Sparks picks could, according to Starsha, be destroyed any minute. Derek Wildstar tries to reason with Sparks, then warn him of the danger, but Sparks blows off the warning. Immediately after, an earthquake and the resulting tsunami kill everyone on the island except for Nova.
As the Argo prepares to depart, Starsha, who wants to remain on Iscandar because it's her home, tells Alex she loves him and runs off. At the last minute, Alex runs to Starsha, asking Derek to forgive him. Derek and Nova wave goodbye to Alex and Starsha, and the Argo blasts off for the return voyage to Earth.
Earth has 131 days left.
The Journey Home
Having obtained the Cosmo DNA from Queen Starsha, the Argo begins the return trip to Earth. The trip is mostly uneventful, but when the Argo initiates one final space warp to bring it into the Earth's solar system, it narrowly misses a shot from the Desslok Cannon, a weapon similar to the Argo's Wave Motion Gun. Desslok orders an immediate warp to follow the Argo, but without time to calibrate, both ships collide. Desslok releases a radioactive sleeping gas, then leads a boarding party onto the Argo. Derek Wildstar leads a team to confront Desslok and finally meets the Gamilon leader face to face, but is partly subdued by the gas. Meanwhile, Nova, with Sandor's help, activates the Cosmo DNA to neutralize the gas, but the gas overcomes her and she collapses, comatose. Desslok retreats but promises Wildstar they will see each other again. His ship warps away before the Argo can fire.
When Wildstar asks Sandor what cleared the gas so quickly, Sandor tells him what happened to Nova. When Nova doesn't wake up, however, Wildstar becomes despondent and goes to Captain Avatar for advice. Avatar consoles him, commending Nova's bravery and emphasizing the importance of hope. He then shakes Wildstar's hand one last time. As the Earth comes into view, Wildstar carries a still-unconscious Nova to the bridge. Just then, Desslok fires his cannon at the Argo. With the Argo unable to escape the shot, Sandor activates his latest invention -- a reflector force field based on the Gamilons' Reflex Gun -- which sends the energy from the cannon back to Desslok's ship. Desslok's flagship is destroyed, and his face disappears, engulfed in flames.
In his cabin, Captain Avatar holds an old photograph of his wife and son as he views Earth with his own eyes. Seeing it, he is satisfied, and dies. As Dr. Sane comes down to the main bridge to deliver the news, Nova begins to stir, and Wildstar takes her in his arms and dances with her on the bridge.
The Star Force returns to Earth in the year 2200, with just over a month to spare.
