Cavalcade D'Amour is divided into three sections, each depicting a romance occurring within the walls of the Chateau de Champs. Legend has it that whoever marries in the Chateau is doomed to an unhappy life. This proves to be the case in 1639 and 1839, but the heroine of the 1939 segment, Corinne Luchaire, is determined to break the jinx. She is convinced that she will prove an unsuitable bride for Claude Dauphin, and he is likewise convinced that he will turn out to be an inadequate groom. But the couple's respective families will not be dissuaded, and the marriage takes place as scheduled? with unexpectedly happy results!

Sylvie, a young woman who believes to be cursed, lives in the town of Carcassonne with her guardian, Mr. Toulzac. He is a retired teacher who wishes to discover the secret of the Cathars, a Christian sect of the Middle Ages that glorified death over life. Sylvie meets Roland, a composer who instills new hope into her troubled mind. Mr. Toulzac then asks her then to renounce the world and go down a secret tomb he has just found.

Based on Sébastien Japrisot's novel, the story revolves around a young girl who suffers from amnesia after surviving a terrible fire.
