Laura (Cameron Diaz) and Kyle (Jon Favreau) are a happy couple, about to celebrate the wedding of their dreams. To help set them off in style, Kyle's buddies organise a stag night that turns out to be unforgettable - for all the wrong reasons. During the debauched festivities, a young stripper is killed and rather than going to the police, Kyle is convinced that he should dispose of the body in the desert. This sets off a chain of events which spirals out of Kyle's control. Hardly the best preparation for the most important day of his life.
