His Hour on AllMovie

Gritzko, a prince of pre-World War I Russia (John Gilbert), is the ultimate ladies' man. Women fall at his feet -- all except for a young but cold British widow, Tamara Loraine (Aileen Pringle). While she's spurning his advances, Tamara is growing ever more fascinated with Gritzko. And for the first time, Gritzko actually feels true love. Tamara doesn't want to become just another conquest, so she insists on returning home. Gritzko complies, but makes sure they leave alone in a snowstorm so that they are forced to seek shelter at his lodge. Tamara, however, keeps him at bay until she faints from exhaustion. When she awakens and discovers that her shirt is unbuttoned, she is convinced she has become compromised. Even though Gritzko hasn't touched her (except to make sure her heart was beating -- at least, that's what he says), he offers to marry her. She accepts, and after the ceremony, he proves his love by telling her that he will leave her alone unless she sends for him. Only then does she admit she has always loved him.
