It's every brother's worst fear: As Aiden and his sister Meg are walking home from school one day, a van pulls over and Meg is kidnapped. There's no way for Aiden to stop it from happening. He's the only witness to his sister's disappearance.

While Meg fends off her kidnappers and plans an escape, Aiden must team up with the FBI to try to find her — tracking down clues only a brother could recognize.
