Taking place in Los Angeles in 1969, Once Upon a Time in Hollywood is about a television star who lost his gleam and his stunt’s efforts to regain fame and success in the film industry, which has become increasingly challenging in the last years of the Hollywood Golden Age. The story sets off with the Manson massacre; five people were killed, including Sharon Tate – the next-door neighbor of the actor, took place in the same year as the background story of the duo.
