Al Capone Does My Shirts: Moose Flanagan and his family move from Santa Monica to Alcatraz Island when his father takes a new job as an electrician and a guard in the well-known Alcatraz prison. Moose becomes friends with the wardens at Alcatraz's daughter, Piper, who regularly gets into trouble in her attempts to earn money to get off of Alcatraz. Piper talks Moose into being part of her money-making schemes, like having inmates on the island do laundry for the kids at school. When the scheme fails and the Warden receives word of it, the children are punished and have to find a new way to spend their time.Moose hangs around the prisoners' rec center in hopes of finding a stray baseball for use in games with the other kids. Moose is only reassured because of his confidence that she will be re-accepted to the Marinoff P. Esther School for people with special needs. Moose and his family's hopes are crushed when the school rejects Natalie.
