Thirtyfive years later, the middleaged Kate Ma Barker Shelley Winters now brutalizes innocent people herself, while indulging her monstrous sexual appetites. She lives by robbing banks with her four sons the pragmatic Arthur Clint Kimbrough, the sadistic Herman Don Stroud, the bisexual Fred Robert Walden, and the loyal, drugaddicted Lloyd Robert De Niro. It all begins in the late 1920s when Ma leaves her husband, George, and her Arkansas home and embarks on her own with her four sons on a robberymurder spree to make her own fortune, while keeping them under a tight leash.When Herman and Fred are arrested and imprisoned for petty theft charges, Ma takes over the group and leads Arthur and Lloyd on a bank robbery spree to gain enough money to get her sons out of jail. The gang is joined by a gunman named Kevin Bruce Dern who was Freds cellmate during his incarceration and his strongly implied lover. The group is also joined by a local prostitute named Mona Gibson, whom Herman frequented before his imprisonment. The gang resorts to more violent action and robberies. ........
