Three men travel together across Europe. For two of them the journey involves a confrontation with the acts of their fathers, who were both senior Nazi officers. For the third, international lawyer and author Philippe Sands, it means visiting the place where much of his own Jewish family was destroyed by the fathers of the two men he has come to know. It is an emotional, psychological exploration of three men wrestling with their past, the present of Europe - and conflicting interpretations of the true facts.
