The life of a tropical fish shop owner is taken over by a fellow fish entrepreneur who happens to be a serial killer. Loosely based on the exploits of two Tokyo serial killers, Sekine Gen and Hiroko Kazama, a husband and wife duo who owned a pet shop and murdered at least four people.

Revered by a following of cinema hipsters (yet still largely undiscovered), Japanese director Sion Sono reaches an impressive new level with this true crime opus, skillfully balancing tense drama with outrageous black humor and never giving in to exploitation. A Japanese Sweeney Todd!
