On the night of September 4th 1998, Isidre and Dolors Orrit disappeared from the San Juan de Dios Hospital in Manresa in unexplained circumstances and without a trace. Isidre was five years old and his sister Dolors was seventeen. Thirty-three later, the case remains unsolved and responsibilities have not been determined. The documentary by Ferran Ureña and Marc Solanes tries to reconstruct the facts giving voice to the family and the role played by journalists such as Paco Lobatón whom, with his TV program "Quién sabe dónde", played a key part in the investigation being carried out. The documentary flawlessly reveals how society and the media back then were not always up to the task of dealing with such tragic events.
