A sudden development in the investigation and a mistake made by one of the thieves confronts the Professor with a serious risk that could lead to his identity being revealed.

The problems inside and outside the National Currency and Stamp Factory are growing. The biggest robbery in history does not allow any mistakes and each time, the tension and fear is rising. What opportunities are there for everything to go well?

A new police plan will make Raquel enter the National Factory of Currency and Stamp, right at the peak of the biggest heist in history. Berlin will be responsible for being the most extravagant host that the inspector has ever seen. What is their plan

Despite the setbacks and to keep more than 60 hours locked up, the mood of the robbers does not decline. The printing of tickets can not go better, surpassing the figures that had been marked and the construction of the tunnel initiates a new phase that will facilitate the perforation. In the police tent, however, the weather has become rare after the assault on the pharmacy. Suspicion begins to settle in Raquel and Angel, both distrust each other despite having been more than partners. Neither policemen nor robbers know that a leak is being planned among the hostages. The brain is Arturo, the director of the FNMT. Will he be able to convince his kidnapping companions to lose their fear and try to escape?
