Lluis Gros, sentenced to 24 years in jail for child abuse at a cinema from El Masnou, asks the Youtuber Carles Tamayo to make a documentary about his case with the aim of proving his "innocence". Tamayo makes contact with the complainants and finds out that the events that sentenced Lluís are just the tip of the iceberg of a longer criminal record which lasted several years.
