A hundred miles away from a scene of a grizzly murder in small town
America, Jill Johnson (Camilla Belle) settles in for a routine night of
babysitting. With the children sound asleep and a beautiful home to
explore, she locks the door and sets the alarm.
But when a series of eerie phone calls from a stranger insist that
she should "check the children", Jill panics. Fear escalates to
terror when she has the call traced. And what the police find turns the
perfect babysitting job into a 16-year-old's worst nightmare.
