Hervé is a tough sea captain in command of the "Duchesse Anne", a rum-trading ship. But the sea dog hides a tender heart and he allows Marie-Douce, a poor slum girl who dreams of seeing the wide world,on board. To have her accepted by the crew, he passes her off as his niece. A seasoned master like him, wise enough to ban alcohol use on his ship, should have known better : a beautiful girl on the deck cannot but unleash the savage instincts of all those men without women.
The story of a gentle-hearted beast in love with a simple and beautiful girl. She is drawn to the repellent but strangely fascinating Beast, who tests her fidelity by giving her a key, telling her that if she doesn't return it to him by a specific time, he will die of grief. She is unable to return the key on time, but it is revealed that the Beast is the genuinely handsome one. A simple tale of tragic love that turns into a surreal vision of death, desire, and beauty.
