This documentary chronicles the bizarre case of a young Frenchman who convinces a Texas family that he is their teenage son who vanished three years earlier. How could they fall for con man Frédéric Bourdin and his wacky story? Through interviews with Bourdin and members of the family and reenactments of events, the story unfolds in astonishing twists. Why did they accept him into their family? Shouldn’t a mother know her own son? Is the family hiding something? Could it really be him after all? This true story is unbelievable.
