An American journalist in Paris embarks on a story about the Holocaust and discovers connections between the past, her present marriage and her unborn child. Beginning as an article on the 1942 roundup of Jews in France as they were sent off to Auschwitz, it soon becomes a journey of self-discovery as the protagonist stumbles upon a terrible secret of a family forced out of their home and a young girl called Sarah who makes an impulsive decision to leave her younger brother locked in a cupboard. A film about the Holocaust is certain to be moving, but the circumstances in this one are harrowing, the truth astonishing, and the coincidences as unbelievable as the tragedy itself. It is a journalist's quest to dig up the lives of others and unleash the truth, but this film show the price of these actions. Sarah's Key takes us from Paris to Brooklyn to Florence and ultimately to the centre of the heart – showing that even the truth has its cost. And the sadness, as much as we try to unlock it, can never be erased.
