Piano tuner and jazz musician Frank Ryan is in Japan teaching bored housewives how to play piano. Then he gets a gig in a trendy underground bar and ends up ensnared with a young woman with a grudge and the crime boss who owns the bar. Drawn into Tokyo Girl's vendetta, Frank stumbles into an underworld where transgressions are paid for by the flash of a razor-sharp cleaver. And for a pianist, that's not a good thing.
