A peacekeeping force from a certain Chinese military region came to the Celia region in the midst of a civil war and joined the UN peacekeeping mission. In addition to undertaking engineering, transportation, and medical tasks, they also formed a six-member special service team, including Captain Bian Xiang, Deputy Captain Song Jianchen, EOD soldiers Feng Zhiyong and Wang Hai, medical soldiers Xie Mengjie, and network genius Qin Muyang. Wang Hai sacrificed his life to cover his comrades, and Lieutenant Zheng Qihan flew to Celia to join the special service team. A plague quietly spread. In the fight against the plague, the Chinese peacekeeping force medical brigade rescued infected Celia civilians day and night. The militants and terrorists in Celia took advantage of the fire and created panic. The special service team escorted a team of international medical experts into the epidemic area and finally defeated the raging plague. In the peacekeeping operations, the feelings between the team members were also heating up. With the mediation of the UN peacekeeping force, the Celia civil war stopped. The special service team accepted the last mission to escort the sacrificed comrades home.
