Accused of triple homicide, Lázaro Mendoza, a former marine, enters the prison, La Rotunda as Dante Pardo to fulfill a mission: rescue Linda, the daughter of Judge Morris.

Tavares, the leader of the gang that leads the prison, assigns Dante control of the courtyard, replacing La Foca. Dante hears that something happens to La Gringa, the young woman who he must rescue.

A map and the instructions of an old assassin, still imprisoned in La Rotunda, take Dante through a tunnel that leads him to Linda's cell. His life is in danger, they persecute him tirelessly.

With the data that Dante gives him about Linda and behind the back of the undercover soldier, Porfirio blackmails the judge and pays half a million dollars. El Elegante is free, but refuses to leave.

Tavares puts Santito in charge of the mission of moving Linda. Dante participates and manages to filter the location of the Ranch, where they take her. Judge Morris sends Jack to rescue his daughter.

After the failed attempt, it is time to remove Linda from prison and do some maneuvers to avoid being discovered. Frida announces to Peniche that she opened an investigation.

The ranch where they have Linda, is surrounded by Morris snipers. The band of the Tavares takes a surprise and in the middle of the shooting, Dante is wounded and deceived.

Peniche gives Dante permission to be absent and manages to get a passport, money and a weapon. He goes over the border and looks for Morris. He gets a call from his son, Pablito.

Although Dante asks her not to call the police, Frida takes a risk and makes contact with an agent, brother of an inmate, telling him that he is a child who lost the couple who took care of him.

When trying to find Pablito's location, Frida discovers Dante's entire history as a former soldier and his rescue mission at La Rotunda, in which he was betrayed and she confronts him.

After Frida visits Linda in Texas, Judge Morris's daughter goes to the prison, in disguise, to help Dante find his son. Santito's father is killed. Tavares swears revenge.

After making the decision to return to the US where Dante Pardo does not exist, nor has problems with the law, Lázaro kisses Frida and invites her to leave with him. Linda and Frida go for Pablito.

In the middle of the chaos, deceiving the authorities and wearing the uniform of a fireman, Dante leaves the penitentiary by the main door of La Rotunda and is released. He says goodbye to Frida.
