Luis Lacasa is a prestigious police inspector from Madrid who suffers from a curious visual disorder: he is unable to distinguish colors. His condition has recently led him to make a serious mistake in an operation, causing a disciplinary suspension. Ramón, his faithful colleague from the Homicide Department, decides to take his friend on a cruise to the Canary Islands, trying to distract him and reconnect with him.

Luis is trying to get used to his new life in Tenerife, although it is very difficult for him. He is reconnecting with Jimena, a daughter he barely knows anymore; getting used to the heat, the slowness of the Canaries, and the impossible bus schedules; and trying to find some stimulating police case between robberies of tourists and assaults in beach bars. Secretly, Luis is trying to take advantage of his.

The Canarias Noir, a major crime fiction festival, is about to open its doors when a corpse appears on display inside the university hosting the event. Luis and Naira suspect that it is a ritual crime, typical of a serial killer. However, the turbulent career of the victim, emerging writer Camila Turino, points in many other directions: a critic, a journalist.

The filming of the Ex Pedición contest, a famous TV reality show in which several couples meet again looking for a second chance, is interrupted when the corpse of Ian, the main star of the show, appears floating. Naira and Luis will have to unmask the murderer among the contestants on the set. Muscled guys, explosive girls, fame, jealousy and passions running high.

Alba and Ángel have organized a dream wedding. At least, until one of the wedding guests collapses dead during dessert. The suspects? The bride's uncles, members of the Irish mafia, the same mafia that Luis has been chasing for years from Madrid. But they are not the only ones. Naira and Luis will have to deal with two boyfriends who are in a dysfunctional relationship.
