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.

When I woke up, I found myself inside an iron grate. Hairi had been proposed to by his girlfriend a few hours earlier. On the way home, he seems to have been kidnapped by someone. I looked into the darkness and there was also his old girlfriend Kageji. Kageji has a debt of 17 million yen, and Hairi used to be the guarantor. He was kidnapped to pay off the debt. In order to participate in the gambling TV "Death Game" broadcast for a mysterious rich man... He says that if he can win the game of life and death, he will not only get rid of his debt but also get a lot of money. If you lose, you die, and if you don't do it, you'll be in debt and you'll be in hell. Can Hairi, who majors in psychology in graduate school, capture special gambling such as "Russian Roulette of Death", "Antarctic Yakyuken" and "Indian Poker"? The battle to the death between Kageji and Hairi begins!!
