1982. A young police officer hardened in the harshest neighborhoods of Madrid accepts a destination in a seaside town with the hope of curing his daughter and, incidentally, gaining some peace of mind. Once there, he is involved in the investigation of the strange murder of the inspector whom he has to replace. The investigations will take you to a beach hotel where a community of elderly Nazis, claimed by many countries for crimes against humanity, lives a heavenly and happy retreat.
