A war between two factions outside the Solar System threatens Earth. A wayward missile in that war hits the sun (and destroys a starliner en route), and this causes the sun's nuclear fusion to go out of control. In one Earth year, unless the fusion is corrected, the sun will burn the Earth and all life will cease to exist. Also, in three years, the sun will explode and destroy the solar system. The Argo, now officially captained by Derek Wildstar, is commissioned (with new cadets) to search
On board the Argo, Commander Wildstar meets former shipmate Cory Conroy. Derek shows Conroy the new Cosmo Tiger fighter, being piloted by Cadet Flash Contrail. In the mess hall, they meet Flash briefly before Derek receives orders to send Flash back home. Mark Venture briefs the crew on where they plan to look for a new planet, but Derek says that beyond a certain point they don't know what to expect. The ongoing war between the two factions intrudes into Earth's solar system, prompting the Ear
To make the journey from Earth to Iscandar, Captain Avatar speaks before the assembled Star Force inductees asking for those willing to make the daring journey to come aboard. In response to his request, a number of volunteers elect to sign on for the trip, including cadets Wildstar and Venture; Nova, a nurse and radar operator; Sandor, an engineer and chief mechanic; Dr. Sane, ship's doctor; IQ-9, a robot with a sense of humour; and others. Meanwhile, Colonel Ganz, the Gamilon commander on Plut
Commander Wildstar orders a warp to the planet Mars to test the crew. As soon as the ship comes out of warp, he has the crew go through sixteen hours of drills, including a simulated attack on Mars and the Argo taking damage and casualties. While the exhausted cadets rest, Jason discovers that the section commanders continue to train even after drills are completed. He also learns that Wildstar trains harder than anyone else, even in his spare time. Just then, the crew are summoned to their bat
The Argo approaches the battle-damaged Legendra, fleeing from the Galman fleet. Wildstar wishes to keep Earth neutral, but the Galmans have other ideas.
Dagon continues his attack on the Argo and the Legendra near Planet Brumas. The Cosmo Tigers destroy several Galman ships, and Dagon ramps up the attack. Ram sends one final message thanking the Argo for its help before the Legendra is destroyed. Commander Wildstar orders the Cosmo Tigers back before continuing the counterattack on the Galman fleet. Dagon orders his flagship and two others to warp while the remaining ships continue to engage the Argo. One ship crashes into the Argo, inflicting h
As the Argo approaches one of Neptune's moons, which is similar to Earth, an attempt on Earth to use the sun's energy to cool it off fails. Meanwhile, Commander Wildstar heads a landing party to locate the source of several radio transmissions coming from the planet. Just then, the party encounters fire from a lone gunman, and they pursue the man, who appears to be from Earth. They find the man, his daughter, and her husband, the latter of whom is seriously ill and eventually dies. When the man
As Dagon continues his attack on the Argo, Derek Wildstar tries to locate the Galman base. He discovers that Galman ships, not satellites, are reflecting the lasers toward the Argo, and launches an attack on them. The Cosmo Tigers provide additional support, destroying the ships. Derek locates the relay stations and orders a surprise attack. Dagon launches a proton missile at the Argo, but the Star Force fires the Wave Motion Gun, destroying both the missile and the base. Dr. Sane tries his bes
As the hijackers take over the Argo's engine room, Jason and Flash discover they are carrying stun rifles and report this to Commander Wildstar. The hijackers demand to be taken to the planet Guardiana and its Queen, who is said to be a legendary space goddess. Leading a team into the engine room, Derek overpowers the hijackers, turning them over to the Bolars. Bemlayze, the Bolar Prime Minister, arranges for Derek to meet him on Berth. Enroute, Derek discovers the hijackers are being executed.
On board the Argo, Dr. Sane operates on Commander Wildstar to remove shrapnel from his arm. When Derek wakes up, he tries to go to the bridge, but Nova orders him to rest, saying she'll take care of him. Meanwhile, Sandor finishes the subspace sonar and installs it on the ship. In space, Feral has two of his ships move into position so they can be detected. The Argo destroys both ships, but the rest of the fleet then lures it to Admiral Smeardom's fortress. With Derek incapacitated, Jason order
Sandor and Homer travel to Earth with Major Cranshaw, one of Desslok's scientists. After meeting the Earth Defense Force's commander, Cranshaw takes one ship to Saturn while Sandor and Homer follow in a second ship. Sandor explains the plan: first, Cranshaw will launch specially designed missiles to form a magnetic shield around the sun. Then Sandor's group will launch special missiles to gather asteroid fragments and send them into the sun. Finally, Cranshaw will launch proton missiles, and the
The Argo begins the first of three warps to Planet Phantom, a distant planet of which little is known other than that it resembles Earth. At Bolar Headquarters, Belmayze orders a fleet to attack and destroy the Argo. Meanwhile, the Star Force receives a distress call from a small planet. Commander Wildstar sends Jason, Flash and IQ-9 to investigate, but just as they leave the Argo, the transmission stops. Derek decides to allow the mission to continue. On the planet, Jason and Flash discover se
On board the Argo, Derek, Nova and Sandor are unable to locate Flash and Jason, who are trapped in a tunnel on the planet. Suddenly, Flash and Jason meet the planet's life center, who asks them to take care of Queen Mariposa. Phantom says that Mariposa has the secret to the planet Guardiana and must be taken somewhere safe. Phantom then returns Flash, Jason and Mariposa to the planet's surface, where a rescue ship from the Argo picks them up. They describe their findings to Derek, who assigns Fl
