It's 1979 and a band of four friends are looking for their way in the music industry. When they finally manage to raise the money to record their first album, they suffer a great disappointment that ends in an encounter with who will be their manager, Fermín Ordoñez.

Discouraged by the result of their first album, the members of Bronco decide to give a final battle to achieve their dream. Quickly in a talent show they are discovered by executives of a multinational.

Fermín gets a tour of the United States and embarks on an adventure of cheap roads and hotels. Eric is pressured by his family to leave the music and Ramiro Delgado replaces him.

Knowing the context in which Ramiro lives, Lupe offers to continue in the band. Fermín gives them excellent news: they will play in one of the most recognized halls of Apodaca. But happiness does not last too long since everything ends in tragedy.
