In 1959, an alien experiment crashes to earth and infects a fraternity member. They freeze the body, but in the modern day, two geeks pledging a fraternity accidentally thaw the corpse, which proceeds to infect the campus with parasites that transform their hosts into killer zombies.

A group of American teenage boys goes south of the border to work for the summer at a Mexican resort. There they encounter many wacky guests and have zany adventures involving a German dominatrix, a music teacher that gets hot when giving lessons, a buxom cook, and an uptight socialite that eventually thaws. More often than not they end up in bed with someone, but one of the teens is holding out for True Love.
