The CIA put Grace Archer and her young daughter, Frankie, under protective custody on a small horse farm in Alabama. When their cover is blown, the CIA wants to use Grace and Frankie as bait to smoke out Marvot, an old enemy. The only person who can help is Jake Kilmer, a rogue agent. Years ago, he trained Grace as an operative so that the CIA could benefit from her uncanny talent for handling horses. They wanted to find out why a French Moroccan underworld kingpin wanted to train two beautiful, wild, and extremely dangerous horses known as "the Pair." The mission was a failure, and Grace, then pregnant, went into hiding, distrusting Kilmer, with whom she was having an affair. Now Marvot has put a bounty on Grace and Frankie's heads, wanting to bring them back to Morocco to train the horses. Kilmer wants to kill Marvot and use "the Pair" himself. Frankie trusts Kilmer; now Grace must find out if she can do the same.
