An Army Ranger and a young widow living vastly different lives meet in a chance encounter on an airplane. He's tasked with trying to find and eliminate an American-born terrorist in the mountains of Afghanistan, and she's trying to rebuild her shattered life in a beach town in Mexico.

While on a mission, Max De Los Santos and his team are being watched, even studied, by an insider. The traitor in the background will become hell-bent on revenge even as the rangers finish the job they were sent to complete, nearly costing Max his life. Max takes a long shot and puts all his cards on the table with Faith, and they decide to try to make a life together after Max's career comes to an end. The newfound love is in jeopardy even after the last shot is fired, but was it the last shot?
