Special Agent Eliot Ness (Robert Stack) forms The Untouchables, an elite squad of incorruptible lawmen, in order to bring down underworld kingpin Al Capone. First televised as a two-part episode of the Westinghouse Desilu Playhouse in April 1959, The Untouchables was later combined into one seamless version for movie theaters titled "The Scarface Mob."

Detective Eliot Ness comes back to town to fight corruption and avenge a former partner's murder with the help of the son.

Federal agent Stack discovers that Lucy is a dead ringer for gangster Gordon's moll and gets her to go undercover in order to recover missing bank robbery loot. This episode was a spoof of the classic crime drama The Untouchables which was produced and filmed at Desilu Studios.
