On an otherwise normal morning, former Special Forces operative Sam Dryden is the target of an unsuccessful attempted abduction. Using his attacker’s cellphone, he learns that another person, a woman named Danica Ellis, is also being targeted. Dryden arrives just in time to save Danica from the assault team sent after her. But neither of them recognize the other, or have any idea why they are being targeted. The only clue is a heavily redacted, official-looking document given to Danica by her stepfather before he was killed.
