Naomi Watts stars as Susan, a single mother of two, working as a waitress in a small town, but everything in her life is not what it seems. Her son, Henry (Jaeden Lieberher), is an 11-year-old genius who not only masters academics, but manages the family finances and acts as emotional support for Susan. When Henry finds out that the girl next door, Christina, has a terrible secret, Henry and Susan take matters into their own hands in this imaginative and emotional drama from director Colin Trevorrow (Jurassic World).
