After months of preparation and seclusion, The Professor and his band of eight recruited robbers begin to attack the National Coinage and Stamp Factory of Spain. Everything goes according to plan, until the police shows up and shots are fired. Hostage negotiator inspector Raquel Murillo makes initial contact with The Professor, and it turns out that one of the hostages, Alison Parker, is a crucial part of the thieves' plan.

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.

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.

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.

Surprised by the escape of a small group of hostages, the robbers and the police are getting entangled into a wild shoot-out. As a consequence, the thieves offer the remaining hostages a deal: money or freedom? Meanwhile, Raquel has to deal with Angel being in a critical condition at the hospital after a mysterious car accident - and with Salva unexpectedly meeting her mother.
