On 28th October 2003, Ronny Tapias, a seventeen-year-old boy from Colombia leaves high school with a friend to go home. A group of young men are waiting on the pavement in front of them, who rebuke and attack him. One of them tells him that he has already been warned, sticking a knife in his chest and killing him.

Carme Gallart, a neighbour of the Pallaresos, disappeared on 18th June 2015. She had planned to have lunch with her friend Joan in Tarragona, but never arrived. When her daughter Monica reports her disappearance, she points out two suspects: José Luis Rodríguez, a friend with whom she has exchanged messages and who is after her, and Ramon Franch, a real estate agent with whom she has a pending lawsuit for fraud. Finally, the investigation yields results: the geolocation of a phone and the cleaning of a car help to clarify what has happened.
