January 16, 1935. Oklawaha, Florida. Eliot Ness, along with Bill Youngfellow and Martin Flaherty, are closing in on Ma Barker, who is holed up in a house along with 2 of her sons, Lloyd and Fred. Ness says they are wanted for everything from bank robbery, kidnapping, to first-degree murder. Now that Ness has found where the Barkers are, he contacts half a dozen state troopers and local police for backup. From a distance, Ness yells at Ma Barker and her boys to surrender and come out with their hands up. Ma Barker goes to a closet, and inside is an arsenal of weapons-- machine guns, pistols, hand grenades, etc., enough for a small army. She fires a chopper at Ness; he jumps behind an 8-foot long wooden flower pot that gets riddled with bullets. Ma Barker throws a hand grenade that almost blows up Bill Youngfellow. Ma Barker is the most vicious outlaw they've ever faced. In a flashback, we see how it all started in Tulsa, Oklahoma years ago: Ma Barker was a church-goer, but always making excuses for her 4 boys who were committing petty crimes, which escalated into serious crimes. In 1927, while the 4 boys were looting a store, Herman got shot by a policeman. Pa Barker finally had the guts to walk out on the bunch. Ma and her 3 boys committed bank robberies, and killed a bank guard; also a kidnapping. They committed crimes in a 10-state area. In 1935, Pa Barker tipped Eliot Ness, and Ness almost caught the Barker gang in St. Paul, Minnesota. Then the Barkers kidnapped a millionaire's son and got $200,000 ransom. Arthur "Doc" Barker and his fiancée Eloise left the gang; Arthur took his share of the ransom and went to Chicago, but all the serial numbers were recorded with the police. Around the first of January, 1935, when Arthur spent a $10 bill, the grocer informed Eliot Ness, so Ness knew Arthur was in Chicago. Ma Barker stupidly sent a birthday cake to Arthur (who was using the alias Clarence Tillman), and enclosed a postcard, "Greetings from Oklawaha, Florida." Art (thetvdb.com)
