As Elliot Ness (Robert Stack) and the Untouchables close in on notorious gang leader Ma Barker (Claire Trevor) and her brood in their Florida hideaway, a series of flashbacks traces Ma's rise to prominence in the criminal world. Forsaking her hometown of Tulsa and her religious scruples, Ma quickly makes a name for herself with a progression of robberies and kidnappings, assisted by her equally venomous sons. Hardly an shining example of "mother love", Mrs. Barker has no qualms about discarding any gang member who has outlived his usefulness--including her own son Doc (Peter Baldwin), who has defected in the company of his girlfriend Eloise (played by a young Louise Fletcher). This episode originally ran with a closing disclaimer, allegedly added at the insistence of J. Edgar Hoover) stating that, despite the events dramatized herein, it was actually the FBI rather than Elliot Ness who ultimately rid the world of the Barker Gang. ~ Hal Erickson, Rovi
