One night in Tokyo, Leo, a young boxer, meets his first love, Monica, an imprisoned sex worker. Caught up in a drug-smuggling scheme, they find themselves pursued by a corrupt cop, a yakuza, his nemesis, and a female assassin.

Tearing through Tokyo at breakneck pace, this riotous lovers-on-the-lam confection from Takashi Miike finds the Japanese maestro at his most hopelessly romantic. Which in Miike-speak means: katana-wielding yakuza, spectral visions, and a vicious, unkillable femme fatale—all the wholesome good stuff!
