At turn of century, George Brent encounters woman on train with whom he strikes up a conversation. Later in new york, he learned she has died suddenly. The details of her death bother him in light of some of their conversation. later he is taken to the home of her brother, a prominent doctor (Paul Lukas) and his beautiful wife (Hedy Lamarr) and son. At the party, Lukas voices concern about his wife's recent strange, and asks for Brent's help. Though Lamarr's performance is rather flat, perhaps deliberately so, Brent and Lukas give strong performances, and Tourneur's direction is effective as always. The film builds well to a strong finish.
