After a partial loss of memory, the daughter of a famous film actor, Karolina Williams, comes to Paris and rents an apartment on Claire Street. Soon she realizes that this beautiful old house keeps a dark secret. Karolina finds, in one of the rooms, letters from a certain Celina dated 1943. Celina was held in the house by force, but she didn’t lose heart and did everything she could to save her loved ones—especially the little daughter. As she works through the mysteries whose roots reach back more than half a century, Karolina discovers keys to her own memory—deep within which hide both pain, faith, and love.
