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.

This provocative tale is a stark reminder of the dark intersection of fame, power, and crime.
