Seven years ago, five-year-old Lexie Mason vanished and her mother Sarah was left to pick up the pieces of her shattered life.

Then one hot August night Sarah picks up the telephone to hear a child's terrified voice whispering, 'Mommy, help, come and get me...' The call is cut off, but not before Sarah's heart soars. The voice belongs to Lexie

Sarah goes to the police, the FBI, friends and her co-workers at the Beaufort County, South Carolina Prosecutor's Office, but none of them can help. Desperate, she turns to Jake Hogan, her closest friend in the world, the man who has stood by her throughout the long years of searching.

Jake is now a private investigator and though he is skeptical - convinced that someone is deliberately tormenting the grief-stricken mother - the attraction he feels for Sarah makes him join her search.

Lexie may still be alive - and they may be able to rescue her.
