Young Ann Mason hears the telephone ring again and she wakes up in a panic. She answer the phone, already expecting the voice on the other end. It is a man’s voice that asks her is “he can come up” to her room and that she is going to die soon. She paces fearfully in the dark and climbs back in bed with hands pressed to her ears.  The next morning, she goes to the police station to talk to the lieutenant about the mysterious phone calls. The lieutenant recognizes her from her previous complaints and merely tells her that the calls must be a prank. She denies his speculations saying that she is new in town and that she cannot think of anyone who would want her to die. The lieutenant suggests that Ann tell the man to come up to her room the next time he calls, and to phone the police immediately after to catch the culprit.  The night of her conversation with the lieutenant, the call never comes, but Ann finds trouble falling asleep just the same. Several nights later, the call returns and Ann answers. When the voice asks if he can come up, she whispers yes and then calls the detective’s number that she received at the police station. She hears a knock on the door and opens it to see a tall young boy just under thirty. He tells Ann that his name is George and explains that his roommate, Arthur, had been the voice on the call. George and Arthur were in the Army and they were talking about psychology and driving people mad with fear. Since their discussion, the two ex-soldiers decided to prank call Ann after picking her number from the phonebook. Suddenly, the detective shows up and Ann covers for George by lying to the detective and telling him that no one ever came up to her room. In the meantime, George hides in her bathroom. Once the detective leaves, George comes back out and thanks Ann for telling the police that this all must be a prank before leaving. Ann falls asleep in peace that night. However, she wakes up when it is still dark and turns on the lamp. She notices that the keys on her bed stand are gone and looks up in horror to see the door creaking open.
