Mr. and Mrs. White are trying to find the monkey's paw. They want to make their second wish for Herbert to come back alive. Eventually they found the monkey's paw and made their second wish. After their second wish, they still had one last wish for something else.
Mr. and Mrs. White hear knocking. The knocking is coming from the front door. Herbert's parents had made the second wish for Herbert to come back alive.
Once Mrs. White hears the knocking she comes running to the door. Mr. White says not to go to the door and to stay. He tries to find the monkey's paw as soon as possible. He wants to make his third and last wish.
Mr. White tires to find the monkey's paw as quickly as he can. Once Mr. White found the monkey's paw he made his third and last wish. When Mr. White made the wish the knocking on the door stopped and no one was at the door when Mrs. White opened it.
