Drugs are flooding San Onofre. Fiorito, a young "Sub 21", steals drug from the lab. Luna visits Cristian, who is under a false identity.

Cristian gets crack through guard Ramos, who in turn asks to the Sub 21. César's plan to become Cristian addicted to undermine the power of the Borges is working.

Diosito wants revenge on Marquitos for stabbing Cristian. Meanwhile, Borges celebrates that the business is going better than ever, and even lets Cristian take a line of coca.

The climate remains tense between Borges and Diosito. At first they are treated with respect, until Diosito asks him to help him find out who killed Mecha and take revenge.

The Borges make an agreement with Pardo, Cristian's father, but Bruni and César will try to avoid it. Diosito continues to search for the truth and interrogates Karina about Mecha's death.

Estela is presented as an intervener of San Onofre in front of the inmates. Borges and his band dismantle the laboratory, preparing for the exit of the prison but Lunati has other plans for them.

Bruni and Pantera along with the Sub 21 take Diosito and Borges to the tree patio where a coffin and a grave await them. The revolt in San Onofre will bring many changes to the prison.
