Thanks to a new technology, Andrés, a young policeman, discovers that he will die in 20 minutes.

Diego has just been voted best young player in Europe and at the age of 20 he is on his way to making his team, Atlético de Madrid, champions of La Liga. But his impulsive and conflictive character makes the club, fed up with his excesses, hire Álex, a withdrawn and lonely psychology professor, to improve his behaviour. The two will have no choice but to learn to understand each other.

When the naked body of a teenage girl is found on the banks of the River Baztán, it is quickly linked to a similar murder one month before. Soon, rumours are flying in the nearby village of Elizondo. Is this the work of a ritualistic killer or is it the basajaun, the ‘invisible guardian’ of Basque mythology? Inspector Amaia Salazar leads the investigation, taking her back to the heart of the Basque country where she was born, and where she hoped never to return. Shrouded in mist and surrounded by impenetrable forests, it is a place of unresolved conflicts and a terrible secret from Amaia’s childhood that will come back to haunt her. Faced with the superstitions of the village, Amaia must fight the demons of her past to confront the reality of a serial killer on the loose. But as she is drawn deeper into the investigation, she feels the presence of something darker lurking in the shadows…

Inspector Amaia Salazar must return to the Baztan valley in order to solve a series of suicides that seem to follow a similar pattern.

Geeky-looking Sebas is a surprisingly good classical musician. He’s also a complete unknown in the criminal underworld, and as a new newbie on the police force, that makes him the perfect man for a dangerous mission: to go undercover as a keyboard player for “Los Lolos”, a cheesy flamenco-trap band, who have been hired to play at the wedding of a local mafia boss’ daughter that a major drug trafficker will be attending. Sebas is keen to take on the mission, blissfully unaware that he will turn out to be even cheesier than Lolo, the band’s lead singer, and fall in love with his sister, Luci. Now Sebas will face a tough choice: remain loyal to his new friends or complete his police mission.

Inspector Amaia Salazar confronts the origins of her nightmares as she unfolds the darkest secrets of the Baztan valley. Part 3 in the Baztan Trilogy.

Juanjo (Antonio Pagudo) is a forty-year-old man who, despite not having low self-esteem due to his baldness, his wife, Inma (Eva Ugarte), obsessed with image and aesthetics, is in charge of making him complex about it. On the other hand, his friend Sebas (Carlos Librado "Nene") is affected by his lack of hair and is willing to do whatever it takes to regain his younger version, something that affects his ex-wife, Sofía (Amaia Salamanca) , and their daughters. Ready for anything, both get into a little trouble to get the money to allow them to travel to Turkey and have a hair transplant. In Istanbul they meet Rayco (Tomy Aguilera), a young reggaeton singer who is having great success, but after discovering his alopecia at a concert, he needs an urgent hair transplant. In this way, the three of them will try to seek happiness through aesthetics, but perhaps they will discover that there is something far beyond the physical.

Cheating the tax man was just too tempting for Andrés. Besides, what are the chances of him getting caught? Well, as it turns out, pretty high! And that’s exactly what happens when a couple of tax inspectors turn up at his company to inform him that he owes the IRS a lot of money.
