May is in love with Alonzo, a detective, but her father will not hear of the match as the young man is not wealthy. So she is delighted to hear that her uncle has left her a house, even though the will states that she must live in it alone for a couple of months in order to get possession. She sets out to live the required time in the house. The housekeeper and her husband conspire to frighten May away so as to get the house themselves. But Alonzo arrives at the house in search of a crook who is wanted. The crook gets into the house and dresses up as a ghost to rob the house. At the same time the housekeeper also dresses as a ghost to frighten May away so as to get the house. The ghosts meet and are frightened at each other as they each think that the other one is real. In the end the crook is captured by Alonzo, who gets the reward that is offered for him, and the housekeeper and her hubby are foiled.
