The Book of Henry

The 11-year-old genius Henry lives in the suburbs and leads an adult life: he protects his younger brother and manages his mother's finances. After learning that the neighbor's stepfather, a policeman, is tormenting the girl next door, he tries to help, but the official ways do not work. Henry develops a rescue plan, but a serious illness prevents him from implementing it himself. He passes the plan on to his mother, hoping that she will finish what she started.
