The Life Mask (1918)

Mrs. Helen Courtland passes a fake check for $25,000 from a millionaire named Woodruffe Clay, who is in love with her daughter Anita. To save the family from a scandal in court, Anita marries Woodruffe, even though she loves Captain Hugh Shannon of the Foreign Legion. During an argument on their wedding night, Woodruffe falls and is seriously injured, and during his recovery, he makes her life miserable. Anita suffers from sleepwalking, and after one episode she dreams of poisoning her husband, she awakens to find him dead. Believing that she killed Woodruffe, Anita travels to Europe with Sarah Harden, her nurse, and there renews her affair with Hugh.
