Frank Mayne, a well-known artist, who had served a twenty-year sentence for a murder he did not commit, returns unexpectedly to his studio, where an amazing scene confronts him. Elaine Bernard, one of his pupils, is cowering over a table, her hair disheveled and her clothes all but torn off her back. Ford Maillard, her fiancé, stands over her, upbraiding her bitterly, while lying prone on the ground, his face covered with blood, is Delna, a Hindoo art student, who possesses occult powers. In the background is a woman whom he does not recognize. It develops later that she is his wife whom he had not seen since his imprisonment, and that the girl is his own daughter. Maillard had arrived at the studio in time to rescue her from the attack of Delna, but, misunderstanding her presence there, accused her unjustly.
