An investigation turned into a documentary recovers the figure of the Valencian in the Mauthausen camp. César Orquín Serra was an anarchist and, as he is described, vain, fabulatory, determined and very intelligent.

He led a gang of about 400 prisoners who were transferred to the Vöcklabrock camp to do work for the state. El Kapo premieres this Sunday in Spain at the DocsValencia festival. The book that Guillem Llin wrote in 2020 together with historian and journalist Carles Senso has now become a documentary.
