Synopsis：The civil war in M country spirals out of control, with rebel forces inciting ethnic genocide and drawing close international attention. However, the United Nations Security Council does not authorize military intervention. Zi'an is commissioned to lead a squad of mercenaries deep into rebel territory to find Dr. Ling Yue of the Red Cross medical team and escort her to safety. Zi'an and his team fight through the jungle, overcoming one obstacle after another, and finally reach the medical team's base, where they find Ling Yue. But Ling Yue insists that she will not leave unless the 70 refugees under her care are also brought out of danger together. From the very first day he became a mercenary, Zi'an learned to prioritize the mission above all else. Now, however, he may have to take along a group of people unrelated to the mission—people who could even hinder their successful completion of it. These well-trained mercenaries must make a choice between duty and morality. Before Zi'an can make a decision, a new crisis arrives swiftly.
