In the future, the Japanese government captures a class of ninth-grade students and forces them to kill each other under the revolutionary "Battle Royale" act.

It's three years after the events of the original Battle Royale, and Shuya Nanahara is now an internationally-known terrorist determined to bring down the government. His terrorist group, Wild Seven, stages an attack that levels several buildings in Tokyo on Christmas Day, killing 8000 people. In order for the government to study the benefits of "teamwork", the new students work in pairs, with their collars electronically linked so that if one of them is killed, the other dies as well. They must kill Nanahara in three days - or die.

Let the ultimate sexy death games begin! A handful of mysterious Japanese women take part in a deranged web show that makes them strip off their clothes when they lose a round of Mahjong.

Gleefully adding a risqué, wry twist to an ancient game of strategy, this erotic thriller delivers voyeuristic thrills with the friskiness of Seventies sexploitation flicks, providing strange gameplay at every turn!
