Jesse (Ashton Kutcher) and Chester (Seann William Scott) got really wasted last night. The fridge is packed with pudding, their girlfriends - "The Twins" - are ticked off, and somehow Jesse's car has disappeared. So the hapless stoners set out to find the car, which happens to have their girlfriends' anniversary presents in it. But they soon discover that losing the car isn't half the story. High school hottie Christie (Kristy Swanson) is mysteriously hot for Jesse, Chester is a favorite customer at the local topless club, and they owe a suitcase full of money to a transvestite stripper. On top of all that, they're being pursued by a minivan full of geeks, horny "space babes," and a couple of "totally gay" Scandinavian dudes - all trying to find the "continuum transfunctioner," the device that can save or destroy the universe...
