The summer of 1977 finds divided Germany locked in a fierce espionage battle. West Germany's premier spy hunter, ambitious SABINE MAIER, faces off against ruthless Stasi General WERNER HEINRICH. Sabine has filled half a prison with her prodigious arrests of communist spies. Heinrich is the mastermind behind a small army of spy gigolos who prey on lonely women working in the West German government's most secret divisions. Caught in the middle is ladies' man STEFAN MALIK, a reluctant Romeo, forced to do the general's bidding or rot in a Stasi prison. Just when victory seems within her grasp, Sabine's worst fears are realized. The Stasi has infiltrated the highest ranks of West German intelligence and Heinrich's well-placed mole sees her every move. The number of women spying for love is growing by the day. To stop the hemorrhaging, Sabine risks everything on a cutting-edge technology that promises to identify subversives. The ingenious system soon picks up the scent of Stefan, who is targeting the Chief of the Chancellery's secretary. But Stefan has an agenda of his own, and when Sabine's master tradecraft exposes it, she lays a risky trap to blackmail him into unmasking the mole. With the security of the West at risk and Stefan's life hanging by a thread, these unlikely allies conspire to outwit the Stasi spymaster and his henchmen.
