Battle Royale (2000)

At the dawn of the new millennium, Japan is in a state of collapse. Unemployment is endemic and school violence is out of control. The beleaguered government retaliates with Battle Royale... Each year, a randomly chosen class is pitted against itself on an abandoned island in a cruel game of survival. The rules of the game are simple: 1) it lasts three days; 2) Each player starts with food, water and a "weapon"; 3) if more than one player survives, everyone dies (by detonating special electronic necklaces; 4) there is no escape. As the game progresses, terror and panic challenge the students' fragile trust in each other. But despite the game's brutality, the adolescent players remain obsessed with their crushes, their petty grudges - and their dreams...
