Kanako lost her husband in an accident five years ago. She was single-handed and her family finances were tight, so she worked night shifts to raise her son, Tetsuro. One day, when Kanako gets drunk and comes home, she falls asleep. Tetsuro, who came to see how she is, gets lustful and attacks his mother who is indecent. The next day, Kanako, who knew her fact, decided to face her son's sexuality with her own body.
