In director Antoine Fuqua's (Training Day) action-adventure film, Bruce Willis stars as Lt. A. K. Waters, the loyal veteran officer of a Navy S.E.A.L. unit. When he's sent into the heart of Africa, the usually hard-bitten Waters finds himself deeply conflicted at having to choose between following orders and the dictates of his own conscience. Lt. Waters travels to war-torn Nigeria to rescue Dr. Lena Kendricks (Monica Bellucci), a U.S. citizen who runs a mission in the countryside. But when Lt. Waters arrives, Dr. Kendricks refuses to abandon the refugees under her care. She implores Waters to escort them on a dangerous trek through the dense jungle to the nearby border of Cameroon. During the journey, the S.E.A.L.s find themselves the unwitting guardians of a man sought by the rebel militia. This further endangers their already hazardous mission. But all the while it strengthens resolve to protect Lena, for whom he has unexpectedly developed feelings, and the refugees, and to deliver them safely across the border.
