Marco (Mario Casas) is a young businessman who manages one of the most successful technological companies in the world, ALVA, which has just launched its latest prototype into the market - CYCLONE, an electric car propelled by turbines that turn wind into energy. His friend and classmate Diego works with him, along with the latter's wife, Bárbara, the efficient marketing manager of the company. Eva, a young, ambitious engineer who has a lot to hide, also joins the team, and she will disrupt the balance at work, both emotionally and professionally, between the two business partners. In spite of being a popular guy, Marco, unlike Diego, doesn't have an exciting social life. He is a solitary man, and no one has access to the intimacy of his soul, apart from his psychologist, SARA, on whom he is emotionally dependent. Marco is haunted by a huge number of ghosts from his past and, although he tries hard to scare them away, he only finds comfort in sport and in frequenting a private club. People go there just to get pleasure and give free reign to their wildest erotic fantasies, without fear of falling in love, as everyone has to wear a mask to hide their faces. But everything changes when Marco meets Carol, the new educational psychologist who looks after his brother José, an 18-year-old boy with problems of autism, with whom he has a difficult relationship. With her, he will also meet his worst enemy - himself. Thanks to her, he will discover that it is never too late to love, even if it brings some pain along with it.
