Kaiji Ito moves to Japan after graduating from high school. Unable to find a job and frustrated with society at large, Kaiji spends his days gambling, vandalizing cars, and drinking booze. Two years later and his life is no better. A debt collector named Endo arrives to collect money owed. The debt collector offers two choices to Kaiji: spend 10 years paying off his loan or board a gambling boat for one night to repay his debt & possibly make a boat load of money. Could the debt collector Endo actually be setting up Kaiji? One way or another, for Kaiji it's going to be the night of his life.

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.
