As a war rages on between two factions outside of Earth's solar system, Cadet Jason Jetter sees his parents off on a sightseeing tour of space. However, a stray missile from the war strikes and destroys the space tour bus and also hits the sun. On Ea... (more)rth, Jason learns that he will be assigned to the rebuilt Argo. He meets Captain Derek Wildstar, who assigns him to KP duty, much to his chagrin. Wildstar learns that he will be in command of the rebuilt Argo and is reunited with former shipmates Sandor and Mark Venture. He is also given an assignment: the activity on the sun has ramped up so much that, left unchecked, it will destroy the Earth in one year and the entire solar system in three. The Star Force is charged with finding a new planet for Earth's inhabitants. Knowing Jason is unhappy with the assignment, Derek goads the cadet into sparring with him to vent his frustrations. He then consoles Jason on the loss of his parents, saying he too lost his family a long time ago. Derek also says he assigned Jason to such a lowly position so the cadet could prove himself to him and the rest of the crew. Jason accepts the assignment and the challenge, and he and Derek become like brothers.
