After finally achieving the high score on Starfighter, his favorite arcade game, everyday teenager Alex Rogan (Lance Guest) meets the game’s designer, Centauri (Robert Preston) — who reveals that he created Starfighter as a training ground for developing and recruiting actual pilots to help fight a war in space. Whisked away from the banality of his trailer park life to a distant alien planet, Alex struggles to use his video game-playing skills to pilot a real ship, with real lives at stake.
Teen misfits Gary (Anthony Michael Hall) and Wyatt (Ilan Mitchell-Smith) design their ideal woman on a computer, and a freak electrical accident brings her to life in the form of the lovely, superhuman Lisa (Kelly LeBrock). She outfits Gary and Wyatt in cool clothes, surprises them with a Porsche and helps them stand up to jerks Ian (Robert Downey Jr.) and Max (Robert Rusler). But, all the while, the boys must hide Lisa’s existence from Chet (Bill Paxton), Wyatt’s nightmare of a big brother.
