When Doris learns of her mother's difficulty she is moved by her subconscious mind to walk into the villain's room in her sleep.

Towards the next morning, Doris again walks in her sleep and, from a lofty window ledge, she rescues Mary (Edwards), the young daughter of another guest (Ridgely) who had seen Doris go into Ambrose's room and sought to disgrace her.
