Matthew Star may look like the kid next door. But he isn't. He's the kid from the next galaxy. Matthew hails from a planet called Quadris, where many of the problems faced by earthlings are also encountered. Matthew, when still an infant, was forced to flee from Quadris in order to evade the invasion of that planet by occupants of a neighbouring planet. On earth, with his guardian, he has to battle his enemies who come specially to kill him in order to sever his last link with the Quadris peoples to claim sovereignty.
Near Matthew's school a movie is being shot. Everybody looks forward to to take part in the filming. Likewise Walt and Pete, an old friend of Matt's, take part in it. Pete would like to make his big breakthrough as a stuntman and when the professional stand-in jumps off, he takes advantage of this chance. For an extremely dangerous scene he risks even his own life.
