Bully

Marty (Brad Renfro) is a tormented surfer who relies on his longtime pal Bobby (Nick Stahl) for rides to the beach and South Florida bars despite vicious abuse. But when Bobby turns his unwanted attention to Marty's new girlfriend Lisa (Rachel Miner) and her best friend Ally (Bijou Phillips), Lisa decides Bobby's reign of terror must end. Assembling a crew of alienated suburban teens, she forms a deadly plan to get Bobby out of the way once and for all, turning friends into enemies and casual acquaintances into co-defendants in a murder that rocked America to its core.
