Ma Barker's Killer Brood: Tired of being poor, Katherine Barker encourages her kids to steal-starting with the church collection plate! By the time they're adults, Mama's not only planning the clan's capers, but joining them on jobs: "Shoot him, Herman, shoot him!" Under her homespun tutelage, Ma Barker's Killer Brood rob an armored car, kidnap a bank president, set fire to a quack plastic surgeon & even throw a party with Baby Face Nelson, Machine Gun Kelly & "Johnny" Dillinger as guests. Though it plays havoc with the facts, Ma Barker's Killer Brood is how things should have been. Gangbusters: After twice disguising himself as a one-armed man-and getting arrested both times, "Master Criminal" John Omar escapes from prison only to be buried alive in Gangbusters, an oddball "true" anti-crime epic which chooses for its subject not Public Enemy No.1 or Public Enemy No. 2 or even Public Enemy no. 3, but Public Enemy No. 4!
