When a mother dies of heart failure in a doctor's office, the physician--feeling somewhat guilty because he couldn't save her--takes an interest in the woman's young daughter, and makes her his ward, but his fiancé doesn't particularly like it. After he returns from a three-year engagement in Europe, the doctor discovers that his ward is now a beautiful, full-grown woman, and finds himself falling for her--even though she's engaged to his fiancé's brother.

In a spooky hotel on the coast of France, two bands of crooks are working independently of the other in an attempt to steal the inherited fortune of an American girl, Sue Tally. Along the way the heiress is kidnapped, three murders are committed, a girl appears in two places at once, mysterious persons roam about the old hotel at night and mysteriously disappear, and there is a hidden room without any doors.

1924 film by King Vidor
