In 1979, a band of four friends look for a way into the music industry; they manage to raise the money to record their first album, but suffer great disappointment that ends in a meeting with their future manager, Fermín Ordoñez.

The members of Bronco decide to give one last battle to achieve their dream. In a talent contest they are discovered by executives of a multinational.

Fermín arranges a tour of the United States for the group and begins an adventure of highways and cheap hotels; Eric is pressured by his family to leave music and Ramiro Delgado replaces him.

Lupe invites Ramiro to stay in the band; Fermín gives the group excellent news, they will play at one of the most renowned venues in Apodaca, but the happiness does not last long.

Fame begins to open an insurmountable gap between Lupe and Fermín; Lupe, guided by Homero, composes what will become the greatest anthem in the band's history.

Martha passes out, and when Lupe heads to the hospital, he learns that his wife is pregnant; Jovita finds evidence that Ramiro is cheating on her and decides to leave him.

Bronco invites Homero to travel with them on their tour of Veracruz; in the midst of the prosperity that Bronco is experiencing, a tragedy occurs; Homer suffers terrible injuries and dies.

Bronco is mourning Homer's death and the absence of his producer causes everything to come to a standstill; they finally find inspiration in their roots, release a new album and begin a long tour of the United States.

The Broncos are invited to star in a soap opera; the process is strenuous for the band and produces conflicts between its members; things are complicated between Lupe and Martha.

Lupe needs a change and wants his family back; an accident involving his youngest daughter leaves him with an unexpected decision; Fermín agrees with Bronco for one last tour.
