Sasaki (Takumi Kitamura) is a sincere civil servant, working at city hall. Due to his timid personality, he can't properly deal with nasty people, including a single mother on the verge of giving up her own child, another civil servant pressing him to have a physical relationship, and a person who receives welfare benefits unfairly. His passivity leads him to get caught up in a terrible crime.
Unfortunately the movie A Bad Summer is not yet available on HBO Max.
