An elite government hit man (Kevin Costner), after receiving news that he has a terminal disease, decides to give up his high stakes life to finally build a relationship with his estranged wife and daughter, whom he's previously kept at arm's length to keep out of danger.

But when his agency offers him an experimental, potentially life-saving drug in exchange for one last mission, it's an offer he can't refuse—even if it means juggling his two toughest assignments yet: going after the world's most ruthless terrorist and caring for his daughter for the first time in ten years while his wife is out of town.
