A couple of chalk-and-cheese convicts escape from the penitentiary and hit the road. Brainy Clark, a computer whizkid, is going to decipher a map belonging to brawny but dimwitted Lewis, which hopefully will lead to a fortune in gold. But when the pair pick up a sexy, silent hitcher who promptly seduces Clark, things start to get decidedly edgy. Pretty soon the mismatched fugitives and their mute passenger are more nervous of each other than the law! Hip 'n' happening road movie.
