A non-linear tale set in December 1942 in Occupied France. German Captain Karl raids the apartment of the Bertrand family who are believed to be hiding their daughter's Jewish fiancé in a secret room. But the couple have already gone. In retribution Karl seems to kill the Bertrand's son and deports the family. As we follow Karl through the rest of his day, however, and the story wraps around to before the events of the opening chapters, we realise that Karl has actually helped the fugitives to escape as redemption for the terrible deeds he has committed in the war.
