One of the most feared Chicago mobsters Sam Giancana clawed his way to the top of the Mafia hierarchy by starting as a hit man for Al Capone. He was known as one of the best vehicle escape artists, a tenacious business man, and a ruthless killer. He partied with major stars such as Frank Sinatra and Marilyn Monroe and did business with agents ranging from the CIA to the Vatican to the shah of Iran.

When politician Joe Kennedy gave Giancana the chance to use mob muscle to get his son John elected, Giancana jumped at the task. But the Kennedy brothers double-crossed him, waging full-out war on organized crime throughout the United States. And Giancana went after them.
