A young man decides one day to start killing yakuza. After he kills his first two he gets roped into helping a wannabe gangster and his bumbling underlings to perform a hit. While things work out in the beginning, this young psychopath quickly becomes more trouble than the gang expected. Will they be able to rid themselves of him, or will they be his next victims?

For his fourth full feature, Toyoshi Toyoda has abandoned the theme of the angry young man, examined in depth in Pornostar, Blue Spring and 9 Souls. Kuchu Teien is, on the face of it, more a drama, a character study, than a typical Toyoda genre flick. Yet within this beautifully structured and photographed film, there lies a dark soul. Ostensibly the story of a happy family, it becomes increasingly clear as the movie progresses that the Kyobashis are anything but. Despite a family agreement that they are all open with each other, the entire household knows the opposite is true.
