In 1942 Paris, gifted architect Lucien Bernard accepts a commission that will bring him a great deal of money --- and maybe get him killed. All he has to do is design a secret hiding place for a wealthy Jewish man, a space so invisible that even the most determined German officer won't find it. But when one of his hiding spaces fails horribly, and the problem of where to hide a Jew becomes terribly personal, Lucien can no longer ignore what's at stake.
