Sinister music maestro Svengali can control the actions of women through hypnotism and his telepathic powers. When a pupil he has seduced announces she has left her husband for him, he uses his powers to cause her suicide and promptly forgets her. He meets a beautiful model, Trilby, and becomes infatuated with her, but she, in turn, falls for a young artist called Billee who also loves her.
