Before Dallas

Using Frank Sinatra as a go between, the Kennedys secure Mafia boss Sam Giancana's help to win the presidency. But when Attorney General Bobby Kennedy declares war on the mob, the favor turns to betrayal. This sets off a chain of events that includes the mysterious death of JFK's mistress, Marilyn Monroe, and an elaborate conspiracy by the mob to assassinate President Kennedy in Chicago, a year before the events in Dallas.
