蓝胡子是一位当地非常有名的富翁，他结果很多次婚，但每一任妻子最终都落得下落不明的下场，这让当地人感到非常的害怕。蓝胡子看上了凯瑟琳（萝拉·克雷顿 Lola Creton 饰）和安妮（达芬妮·百维 Daphné Baiwir 饰）两姐妹，最终，安妮成为了蓝胡子的下一任妻子。 蓝胡子虽然长相怪异，但是对待安妮非常的温柔，这让刚开始胆战心惊的安妮多多少少放下了防备。一天，蓝胡子要出远门，临走之前将一串钥匙交给了安妮，他告诉安妮，这串钥匙可以打开城堡里所有的门，但是只有位于城堡最底层的那扇门万万不可打开。丈夫的这番言语反而激起了安妮的好奇心，她决定以身试险。In France in the mid-'50s, Catherine (Marilou Lopes-Benites) enjoys toying with her older sister, Marie-Anne (Lola Giovannetti), by reading her the story of the murderous and oft-married Bluebeard, embellishing the story with plenty of gore and scaring the girl out of her wits. As Catherine rereads the story, we're taken back to the year 1697, as Lord Bluebeard (Dominique Thomas) prepares to make Marie-Catherine (Lola Créton) his seventh wife. Marie-Catherine's youth and innocence make her an especially attractive quarry to Bluebeard, and rather than murder her right away, he decides to wait a while in order to savor the terrible joy of claiming her life. However, as Bluebeard becomes caught in a cycle of events that keep him from following through on his wife's murder, the two slowly become something like a normal couple and Marie-Catherine begins to turn the tables on her spouse.
