Saori lives alone with her son Makoto after her husband disappeared years ago. Makoto once went through a troubled period, but recently found purpose in his school club, restoring peace to their home. During a home visit, his teacher Abe claims the faculty plans to expel Makoto from the club because of his past behavior. As Saori despairs, Abe offers to make the problem disappear on one condition: she must surrender her body to him. While her son is away at summer camp, the teacher uses that threat to force himself on her.
