This program covers the exciting histories of some of the most well-known gangsters in American history: Bonnie and Clyde, Al Capone and John Dillinger.

Never before has a gallery of cops, robbers, and daredevil crooks ever been assembled into one collection. Using FBI and police film, archival footage, and rare photographs, this story traces the life of Al "Scarface" Capone, Machine Gun Kelly, and many other Depression Era gangsters of the 1920s and 1930s.

In 1932, a cop is killed and Frank Wiecek sentenced to life. Eleven years later, a newspaper ad by Frank's mother leads Chicago reporter P.J. O'Neal to look into the case. For some time, O'Neal continues to believe Frank guilty. But when he starts to change his mind, he meets increased resistance from authorities unwilling to be proved wrong.
