Before Earth Day 1996, the closest Bud (Pauly Shore) and Doyle (Stephen Baldwin) had ever come to a garage dump was the floor of their apartment. So when their ecology-conscious girfriends ask them to stop wasting time and start cleaning waste, the dimwitted duo make it clear that they'd rather talk trash than pick it up. But their world suddenly changes when they're accidentally trapped inside Bio-Dome - a yearlong scientific ecological experiment with no fast food or cable television! Will Bud and Doyle adapt to their newfound habitat or will their very presence spell extinction for them, the project - and perhaps the entire planet!?!
