November 1962. First morning of the Price Circus. Thousands of young people congregate to sing and dance the songs of the most leading groups of the moment. The show is about to end, when a boy jumps on stage, it is Robert Aguirre, who with all the nerve of the world begins to play a song. Those responsible for the security of the concert take Roberto off the stage, but Guillermo Rojas, mixed among the public, has already retained his name.

Upon leaving the Price, Guillermo intercepts Robert and proposes to him to be part of his new project: Futura. His idea is to convince Don Alfredo, the president of Golden Records, to bet on rock and create Futura as the new sub-label of the record company. The reality is that Golden has in its portfolio folkloric music, singers of copla and even the prodigy Marisol, but Guillermo is clear that with rock there is a future, and so he manages to pass over Pedro Zabala (current director of the company) and receive from Don Alfredo an office and a secretary. It has a period of three months to present a proposal that convinces the board of directors.

That secretary is Maribel Campoy, a talented young woman trained at the conservatory. Despite his initial doubts, Guillermo knows how to see the talent of the girl.

Can he convince Golden Records to bet on Robert? Will Maribel be able to enforce herself in a world of men?

45 Revoluciones is the story of a group of young people trying to make their way in the fierce music industry, about their difficult beginnings and how they will be able to do everything to pursue their dreams.
