Knowing that the police won't try to storm the building again after their first failed attempt, the robbers start to use the hostages to print money, to dig a tunnel for their escape, and to negotiate with the police. Raquel, who quit due to a verbal argument with Colonel Prieto after the failed rescue mission, meets a strange gentleman at a bar and gets suspicious. Because of Alison's phone, the police is able to identify 2 of the robbers, Tokyo and Rio - and that's not the only phone the robbers missed to collect.

Monica Gaztambide, the secretary and pregnant mistress of the chief of the Factory, Arturo Roman, gets shot by another robber, Denver. While Raquel is in negotiations with The Professor about the hostages and consults with Prieto and her colleague, sub-inspector Angel Rubio, she gets an important private phone call from her mother, delivered to her by the strange gentleman she met at the bar, Salva. When Moscow learns that his son, Denver, shot a hostage, he wants to give up himself - which leads to another hostage being shot at.

Listening to shots being fired inside, Raquel decides to enter the Factory to ascertain that all of the hostages are still alive and well. The police tries to use this opportunity to win over one of the robbers to cooperate with them - while Angel is on to Salva, who seems to grow closer to Raquel. Also, a deep secret is revealed about Berlin, and it shakes up the dynamic among the robbers.

When someone once again interferes with the police investigation, Raquel and Angel have to question each other's loyalties and friendship. In the light of Monica's well-being, Arturo comes up with a risky escape plan for them and a group of a few other hostages. Rio is faced with a difficult decision that involves his future, and that of his lover, Tokyo.

While the police comb the country house in Toledo in which The Professor and his band planned the heist, the robbers' nerves reach a breaking point within the Factory. At odds with each other and uncertain about how to proceed, Tokyo and Berlin get into a fight - leaving one of them in distress. Also, Salva meets Raquel's ex-husband and forensic expert Alberto Vicuna - which doesn't end well for him.

After being captured involuntary, Tokyo is questioned by the police, especially about the real identity of The Professor. Inside the Factory, Berlin's recent actions are being questioned by his fellow criminals - which leads to a revolt among them after an execution. Also, Salva is being rescued at the police station by Raquel.

During a conversation with Salva at the bar, Raquel spots a tiny detail that gets her mind racing. After confessing a long-held secret, Moscow loses his son's trust and Denver is comforted by Monica. A contingency plan to free Tokyo hits a snag, forcing her to improvise.

With one of their own critically injured, the robbers race against time to save his life and to finish the tunnel before they get caught. After being removed from the case due to her relationship with The Professor, Raquel sets out to conduct her own search for the mastermind.

The Professor's mole attempts to pass along his message to the person inside the tent. Denver's jealousy toward Mónica and Rio's friendship heightens.
