A mysterious woman arrives at the castle of Saint Denis, in the heart of Languedoc, demanding to see the Count of Rennes and Hainaut. She claims to be his wife but the count thinks that the poor woman has lost her mind because she arrives wearing a threadbare habit and tells a very strange story: she is not his wife, his wife died years ago and yet something on the face of that deranged nun is familiar to the Earl of Rennes. Is it the lady in the tower, the secret wife, the one who captivated your heart in your early years, or is she just an evil impostor?
