The documentary's narrator is Dory Sontheimer. This is her story: as a Spanish native and pharmacist, her life took a sudden turn when in 2002, her mother died and she discovered seven boxes perfectly marked and neatly lined up inside a closet. They were full of photographs, letters and family memories, and seemed to form part of a puzzle, set up deliberately so that as she opened them up, she would rebuild her origins - a story very different from the one her parents had told her. Her family was Jewish and her maternal and paternal grandparents, uncles, aunts, and cousins were victims of the genocide committed by the Nazi regime.
