Los Angeles, the sixties of the last century. The golden age of television is beginning to fade away. The ratings of even the most popular TV shows, movies, and television series are being downgraded. Under these circumstances, actors have to look for new ways to earn a steady income and realize their ambitions. One of the two main characters in "Once Upon a Time in Hollywood 4k" is Rick Dalton. He is an actor who became famous because he played the main role in the popular series. He was at the peak of fame for over five years, but now the actor understands that if he stays on the television, his career can be destroyed. For this reason, the main character is trying to move into the world of big cinema. But that attempt is a failure. Then he returns to TV to participate in popular programs. At the same time, he is considering moving to Italy, a country that shoots a lot of low-budget westerns. For the actor, this is a good opportunity to earn some money and to extend his career. The second main character in the film is a stuntman and Rick's assistant, who knows how to find adventures.
