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..
