When a Stranger Calls

Whatever You Do, Don't Answer The Phone.

A babysitter arrives at a sprawling suburban home for what seems like an easy night's work. When her phone begins to ring with calls from an unseen caller asking the same chilling question—"Have you checked on the children?"—she realizes she is not alone. As the calls grow more menacing and the threat draws closer, she must survive a night of escalating psychological terror in a house that offers nowhere to hide.
