Surviving one death-defying game after another, Kaiji Ito (Tatsuya Fujiwara) manages to erase all of his debts. But within a year, he finds himself once again among the so-called “dregs” of society, choking under a new mountain of debt.
Eager for another shot at turning his fortunes around for good, Kaiji earns a chance to take on a monster pachinko machine with a billion yen payout; a beast of a machine dubbed “the swamp.” On paper alone, it poses a formidable challenge, but under the tight control of the illegal casino’s ruthless manager, Seiya Ichijo (Yusuke Iseya), the machine is 100 percent unbeatable. What’s more, a dark and telling secret exists between Ichijo and Kaiji who are the only two to have ever walked across a steel beam 300 meters in the air between two skyscrapers without falling to their deaths.
Now with the “swamp” controlled by his biggest rival, Ichijo, Kaiji must turn to some unlikely fellow “losers” for help in Hiromi Ishida (Yuriko Yoshitaka), Kotaro Sakazaki (Katsuhisa Namase) and Yukio Tonegawa (Teruyuki Kagawa), the man who impeded his every step in the first movie. All four have their own reasons for the current depravity of their lives, but they all share one common trait: an insatiable desire to win back their lives in what is sure to be their last chance.
