On the day before her wedding to Kenichi, Hiroko accidentally kills her landlord and discovers he has been spying on her. Making her escape with the landlord in a suitcase, she drives to a forest near Mount Fuji where she plans to leave the body and, after her big day, turn herself in to the police. There she runs into Fukuko, a girl who is trying--and failing--to commit suicide by hanging herself from a tree. However, Fukuko offers to help Hiroko dispose of the corpse on the condition that Hiroki aid in her suicide. Before negotiations can go much farther, the two women learn they are not alone in the forest and are soon on the run from a menacing motorcycle gang and a frantic young cop on a bicycle.
