Bluebeard is a wealthy and powerful, yet frighteningly ugly, aristocrat who has been married several times to beautiful women who have all mysteriously vanished. When Bluebeard visits his neighbour, a noblewoman, and asks to marry one of her daughters, the girls are terrified. After hosting a wonderful banquet, he chooses the youngest daughter to be his wife - against her will - and she goes to live with him in his rich and luxurious palace in the countryside, away from her family.
Bluebeard announces that he must leave for the country and gives the keys of the château to his wife. She is able to open any door in the house with them, which each contain his riches, except for an underground chamber that he strictly forbids her to enter lest she suffer his wrath. He then goes away and leaves the house and the keys in her hands. She invites her sister, Anne, and her friends and cousins over for a party. However, she is eventually overcome with the desire to see what the forbidden room holds; and she sneaks away from the party and ventures into the room.
She immediately discovers the room is filled with blood and the murdered corpses of Bluebeard's former wives hang on hooks from the walls. Horrified, she drops the key in the blood and flees the room. She tries to wash the blood from the key, but the key is magical and the blood cannot be removed. Fearing for her life, she reveals her husband's secret to her visiting sister, and they plan to both flee the next morning, but Bluebeard unexpectedly comes back and finds the bloody key. In a blind rage, he threatens to kill her on the spot, but she asks for one last prayer with her sister Anne. At the last moment, as Bluebeard is about to deliver the fatal blow, the brothers of the wife and her sister Anne arrive and kill Bluebeard. The wife inherits his fortune and castle, and has the dead wives buried. She uses the fortune to have her other siblings married, and eventually remarries herself, to a man she loves, and moves on from her horrible experience with Bluebeard.
