BOY GENIUS, 12-year-old Emmett (Miles Brown of Blackish) is an award-winning junior at Heart High School, where he's applauded for his academic prodigy status but doesn't have a large group of friends. He goes to school with his older brother, Luke (Skylan Brooks), who's a talented visual artist but gets into trouble -- and he has an unrequited crush on the older Tonya (Arabella Monae). When a string of thefts starts plaguing both staff and students, Principal Ally (Nora Dunn) accuses Luke of the crimes, convincing Luke's single mom (Tracie Thoms) to send her older son to a special boarding school. In order to prove Luke's innocence and keep his family together, Emmett teams up with his SAT test-prep tutor, Mary (Rita Wilson), who's also a crime-thriller novelist, to solve the mystery of Heart High School's robberies.
