Kaiji Ito transfers to Japan after graduating from high school. Unable to find a work and also aggravated with culture at large, Kaiji spends his days betting, vandalizing vehicles, as well as drinking alcohol. 2 years later on and his life is no much better. A financial obligation collection agency called Endo gets here to gather cash owed. The financial debt collector offers 2 options to Kaiji: invest one decade repaying his car loan or board a betting watercraft for one night to repay his financial obligation & possibly make a boat lots of cash. Could the debt enthusiast Endo actually be establishing Kaiji? Somehow, for Kaiji it's mosting likely to be the night of his life.
