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.

While Nairobi, one of the robbers, oversees the continual progression of printing new money, Arturo's condition worsens rapidly. The Professor negotiates with Raquel to let a medical team into the Factory, and Angel sneaks in as a Trojan horse disguised as a nurse to get more informations from inside. Meanwhile, the police tries to find another way into the building, which looks promising until they find out that they were secretly discovered and have to abort the mission.

Rio has to process a shocking message via a news report that they watch on television. Berlin, the leader of the robbers inside the Factory, is forced by Tokyo to confess to The Professor that he ordered Denver to shoot the hostage Monica. A new lead in the investigation, thanks to surveillance footage and a mistake done by one of the robbers, Helsinki, confronts The Professor with the serious risk that his identity could be revealed to Raquel and the police.

After almost getting caught by Raquel at the scrapyard, The Professor has to find a way to scare of a witness that could reveal his identity. One clue he deliberately left behind helps the police to identify Berlin, who seeks revenge once his own name is revealed and slandered in the media - which leads to an unexpected discovery. Meanwhile, the police is searching for a mole in their own midst.

When Rio is captured, a distraught Tokyo turns to the Professor for help. Armed with a bold new plan, they reunite the team in order to rescue him.
