One of the prisoners is Mares, a former member of the International Brigade in the Spanish Civil War. He has been allocated the Alsatian bitch Rita, and is secretly training her in a different way. He just pretends to beat her and at night, he goes and feeds her leftover scraps of food. Mares is planning an escape with his fellow prisoner Benda. - IMDb
