Set in the 1990s, this film uses black humour to cast a sharp, satirical eye at the problems facing modern Japanese families. Hiroshi accidentally hits a young woman with his car and flees in panic. He confesses to his wife, Yoko, who persuades him to keep quiet as his arrest would mean the end for their already troubled family. Their daughter is having an affair with a married man, their son is being bullied and refusing to go to school and their grandfather is becoming more difficult. Yoko urges the family to move the car into the living room in order to destroy the evidence by taking it apart. Hiroshi finally decides to do the honest thing but a series of bizarre incidents then ensues...

A composer who can no longer compose music is led back to the past by his mother's voice. As a boy in the past, he encounters various characters, including a wild samurai and a king of the mountain forests, and arrives at the Paradise of Paradises.
