Andrew is disputing the custody of his daughter, Samara, and shows signs that he is an unbalanced man during a conversation with Sarah. When the security system agent, John Denton, arrives in the house for maintenance of the alarm system, Sarah feels secure. However, when a mark with 13 is found in one room, Sarah realizes that she is in danger.
