When Margaret and Steve Frawley come home to Connecticut from a black-tie dinner in New York, their three-year-old twins, Kathy and Kelly, are gone. The police found the babysitter unconscious, and a ransom note from the ´Pied Piper´ demands eightmillion dollars. Steve´s global investment firm puts up the money, but when they go to retrieve the twins, only Kelly is in the car. The dead driver´s suicide note says he inadvertently killed Kathy. At the memorial, Kelly tugs Margaret´s arm and says - ´Mommy, Kathy is very scared of that lady. She wants to come home right now.´ At first, only Margaret believes that the twins are communicating and that Kathy is still alive. But as Kelly´s warnings become increasingly specific and alarming, FBI agents set out on a desperate search.
