The Untouchables S03 E20 The Maggie Storm Story

"The true story of FBI man Eliot Ness's savage war on the notorious mobsters Al Capone left behind!"

Chicago, after the Repeal of Prohibition; (so this would be around 1934). With booze legal, the racket czars step up their dealings in narcotics. Ness and Lee Hobson are chasing 2 dope-pushers, one of them is Benny Rivas. After the shootout, one hood is dead; Benny moans, ""Get me a priest."" Ness finds heroin on him; wanting to die with a clear conscience, Benny says, ""808"" and dies. That leads Ness to Maggie Storm's 808 Club.
