Professor Juno B. Tidewater (Leon Danmun) is traveling through Ireland with his two daughters when he happens upon a castle. When they are told it is haunted, the girls decide to return to the hotel, but the professor remains. He is greeted by the Hindu caretaker, who receives a letter informing him that his master has died. So the caretaker tells Professor Tidewater about the castle's history -- its owner once unsuccessfully vied for the hand of Betty Truesdale (Marguerite Marsh). She preferred his rival, Captain Bob Lambert (Vernon Steele). The two men wound up in a duel an hour before the wedding, but instead of guns, a venomous snake was used. The snake bit Lambert, and Betty came in as he was dying. She begged to go with him, so the Hindu released the snake once again, and it bit her. They died in each other's arms and then, as ghosts, journeyed around the world on an ethereal honeymoon. The double exposures at the end of this very strange film were so crude that even audiences of the day found them ridiculous.
