The Last Ship opens with a global catastrophe that nearly decimates the world’s population. Because of its positioning, the Navy destroyer U.S.S. Nathan James avoids falling victim to the devastating tragedy, but now, Captain Tom Chandler (Dane) and his crew must confront the reality of their new existence in a world where they may be among the few remaining survivors. Rhona Mitra (Strike Back) plays Rachel Scott, a strong-willed, intelligent and fearless paleomicrobiologist assigned to the ship. Adam Baldwin (Firefly) is XO Mike Slattery, a former homicide detective and Chandler’s second-in-command.
