Plot

The film, a swirling drama of love and death, is loosely adapted from Nathaniel Hawthorne’s 1860 novel The Marble Faun. Princess Maria (Elena Sangro) is married to the Duke of Helgoland (Ugo Bazzini), the leader of an anti-government plot about to be exposed by their house guest Count Giorgio (Carlo Gualandri). Giorgio tries to involve Maria, and in his fatal fight with Helgoland, her husband is killed using the knife that Maria hands to Giorgio. Forced to flee, they meet up again in Rome, where Maria has changed her name to Myriam and Giorgio has become a monk. Giorgio still desires Myriam, who rejects his advances, and she convinces her suitor Donatello (Giorgio Fini) to kill him.
