Everything Goes Wrong

Jirō Sugita is the son of Keigo Nanbara, a business man, who is constantly at odds with his mother Misayo. The two begin a physical relationship with a girl from the group, who has a crush on Jiro, but he is decidedly cooler towards the affair. The following day, Nanbara catches up with them at a rest stop and, in a struggle, brutally assaults Nanbara with a wrench, nearly killing him. The two continue their frantic battle, only to collide.
