1942, Paris. Architect Lucien Bernard accepts a commission that will bring him huge wealth - and maybe a death sentence. He has to design a secret hiding place for a wealthy Jewish man, a space so invisible that even the most determined of Nazi soldiers won't discover it. When one of Lucien's designs fails horribly, the problem of hiding a Jew becomes personal, and he can no longer deny the enormity of his project. What does he owe his fellow man, and how far will he go to make things right?
