Under cover of darkness, an American family moves into a villa in Cholong-sur-Avre in Normandy.
Fred Blake, the father, tells everyone he is there to write a history of the Allied landings.
His wife Maggie gets involved in a local charity; their teenage children enrol in the lycee.
At first glance a family like any other. But Fred's real name is Giovanni Manzoni - an ex-Mafia boss who has grassed and is now part of the FBI's witness-protection program. And his record in other locations would indicate that his cover is not likely to last very long.
