Ruby (1992)

An exploration of certain conspiracy theories surrounding the JFK assassination from Jack Ruby's perspective. Ruby owns a run-down strip club in Dallas, and does what he can for credibility, both by giving information to the FBI and by doing the odd favor for his mafia contacts. When hitman Action Jackson is hit, Louie Vitali asks him to help get crime boss Santos out of a Cuban jail. When they get back, the bosses take his headliner Candy Cane under their wing to develop her career in Vegas. A mysterious government man named Maxwell expresses his displeasure to Ruby over his Cuban activities. Slowly all the pieces of a massive conspiracy begin to emerge to Ruby, who can do nothing to stop it.
