Ryu is a solitary girl whose fragile appearance is in stark contrast with the double life she leads, working nights at a Tokyo fish market and sporadically taking on jobs as a hit-woman. Mr. Nagara is a powerful impresario mourning the loss of his daughter Midori, who has committed suicide. He blames David, a Spaniard who runs a wine business in Tokyo. Mr Nagara's employee, Ishida, was silently in love with Midori and hires Ryu to murder David.
