Sam Dryden, retired special forces, lives a quiet life in a small town on the coast of Southern California. While out on a run in the middle of the night, a young girl runs into him on the seaside boardwalk. Barefoot and terrified, she's running from a group of heavily armed men with one clear goal -- to kill the fleeing child. After Dryden helps her evade her pursuers, he learns that the eleven year old, for as long as she can remember, has been kept in a secret prison by forces within the government. But she doesn't kw much beyond her own name, Rachel. She only remembers the past two months of her life -- and that she has a skill that makes her very dangerous to these men and the hidden men in charge.
