While the two children are asleep upstairs, Jill soon begins to receive anonymous phone calls from a stranger who, most of the time, doesn't say anything and then hangs up. She initially believes it is her friends playing a prank but when she calls them, they deny it. Jill's friend Tiffany stops by but Jill, in fear of getting into further trouble, asks her to leave. Outside while getting back in her car, Tiffany is ambushed. Strange events begin to occur, such as the house alarm going off for no reason, until Jill receives menacing calls from the caller, indicating he can see her. Alarmed, she calls the police, who tell her they can trace the calls if she is able to keep him on the line for sixty seconds. While waiting for the phone to ring, Jill sees a shadow moving in the guesthouse. Believing it is the Mandrakis' son back from college, she goes to investigate but finds the guesthouse empty.
