The film is director Takashi Miike at his most fun and anarchic, a noir-tinged genre-blending yakuza film. Leo (a young boxer) – and Monica (an escort girl) that he accidently meets – get caught up in a drug-smuggling scheme over the course of one (Crazy) night in Tokyo – involving corrupt Cops, the Yakuza – and a female Assassin, who just won’t die.
