During the Libyan evacuation incident, Chinese soldier Lin Haonan rescued war correspondent Hailan while performing a dangerous rescue mission. The two met each other through fighting, but it was the beginning of fate. In response to the country's "military force going out" strategy, the army formed the first peacekeeping combat force "Peacekeeping Infantry Battalion" with Lin Haonan as the commander. Unexpectedly, Hailan also joined the training of the infantry battalion. The two became happy enemies during the training and fell in love with each other. Later, Lin Haonan led the soldiers of the infantry battalion to West Africa for peacekeeping. Before leaving, Lin Haonan decided to break up with Hailan to protect her. Unexpectedly, in the difficult and dangerous peacekeeping work in Africa, Hailan appeared again on a completely unexpected occasion. The two met again and their feelings got closer. In a foreign country under many crises, they faced ghostly enemies, faced the life-and-death threats of artillery fire and even germ warfare, and the two hearts separated and merged several times. In the end, the two successfully completed the peacekeeping mission and were both awarded the "Peace Medal".
