Madrid, summer 2011. Economic crisis. 15-M movement and 1.5 million pilgrims waiting for the Pope’s arrival live side by side in a Madrid that’s hotter and more chaotic than ever. In this context, detectives Velarde and Alfaro must find what seems to be a serial killer. Their against-the-clock hunt will make them realise something they’d never imagined: neither of them are so very different from the killer.

Manuel, a Spanish politician whose high-class lifestyle is based on nefarious and illegal business threatens to break his entire party after a newspaper exposes him to the public eye. Rather than admit to any wrongdoing, he decides to sell out his whole party in an effort to avoid jail time. It's a decision that will put many lives at risk.

Julio Blanco is the proprietor of Básculas Blanco, a Spanish company producing industrial scales in a provincial Spanish town, which awaits the imminent visit from a committee that will decide if they merit a local Business Excellence award: everything has to be perfect when the time comes. Working against the clock, Blanco pulls out all the stops to address and resolve issues with his employees, crossing every imaginable line in the process.

Trying to deceive the Treasury has been a very tempting option for Andrés (Quim Gutiérrez), but he didn't count on them ending up getting caught. And that is exactly what has happened to him. In addition to the million-dollar fine that has fallen on him, he must now move his offices to the Los Caños neighborhood, in the most marginal suburb of the capital, or so it seems to him. But Andrés was taking advantage of a juicy subsidy for having his headquarters there, without him having ever set foot in the neighborhood. Reluctantly, he and his employees move to Los Caños and that is not as bad as they expected... It is worse.
