How do you find your daughter when no one believes she is missing?

Single mother Jess and her daughter Issie have always shared an unbreakable bond. For the last seven years, it's been just the two of them.

That is, until Issie meets Dylan.

When the pair announce their plans to go travelling, Jess is devastated - Issie is only seventeen after all, and Jess doesn’t trust her daughter’s new boyfriend.

And when she stops hearing from her altogether, she's terrified.

With Dylan refusing to talk, and the police unwilling to help, Jess is faced with a mother's worst nightmare.

Can she find her daughter before it's too late?
