Porky's

A group of Florida high school students plan on losing their virginity in 1954. They go to Porky's, a nightclub out in the Everglades, believing that they can hire a prostitute to satisfy their sexual desires. Porky takes their money, but humiliates the kids by dumping them in the swamp. When the group demands their money back, the sheriff, who turns out to be Porky's brother, arrives to drive them away, but not before his minions extort the rest of their money and cause them more embarrassment. After Mickey (who returned to Porky's for revenge) is beaten so badly he has to be hospitalized, the gang becomes hellbent on exacting revenge on Porky and his brother, eventually succeeding in sinking his establishment in the swamp.
