This featured documentary delves into the tangled web of politics, show business, and organized crime in post-World War II America. It traces the unlikely connections between President John F. Kennedy, iconic singer Frank Sinatra, and notorious mobsters, revealing a saga of mutual assistance amidst corruption and betrayal. The film highlights the complex interplay of fame, money, and power, illustrating how these forces helped these figures rise to prominence in a chaotic and corrupt American landscape, ultimately leading to personal and political tragedies.
The documentary paints a vivid picture of Kennedy and Sinatra's ascent, influenced by their ties with the mafia. Kennedy, groomed for power from birth, and Sinatra, rising from humble beginnings, both relied on mafia connections for their successes. As Kennedy's political career and Sinatra's entertainment stature grew, so did their dependence on the underworld. The film culminates in the portrayal of Sinatra's deep involvement in Kennedy's 1960 presidential campaign and the subsequent betrayal of the mafia by the Kennedy administration, suggesting that this complex network of relationships may have played a role in Kennedy's assassination. This provocative tale is a stark reminder of the dark intersection of fame, power, and crime.
