Battle Royale (18)

In a dystopian future, teenage rebellion escalates out of control, and Japanese authorities pass a new law: Battle Royale. Each year, one high school class is selected at random to take part in the ultimate game of survival. The students are stranded on a deserted island with limited food and weapons, and are told to kill one another until only one remains. A 72-hour deadline is imposed by the organisers, and should more than one person be alive after the time expires, then everyone will be killed.
