Lin Haonan, played by Du Chun, is the captain and company commander of the third batch of peacekeeping infantry battalions, and Gao Leng is the soul of peacekeeping infantry battalions.

We should not only strategize, but also lead other peacekeepers to live and die together and advance and retreat together. During the evacuation of overseas Chinese in Libya, the two men got to know each other when they rescued war correspondent Lan Hai in a dangerous rescue mission.

In response to the national strategy of "military forces going out", the first peacekeeping combat detachment "Peacekeeping Infantry Battalion" with Lin Haonan as its commander unexpectedly met the Blue Ocean again in the infantry battalion.

But before Lin Haonan led the infantry battalion to peacekeeping in West Africa, he just broke up to protect the blue ocean. But unexpectedly, in the difficult and dangerous African peacekeeping work, the blue ocean unexpectedly appeared.

The two meet again, facing the ghostly enemy under the crisis in a foreign land. They finally successfully completed the peacekeeping mission and were both awarded the "Peace Medal".

It can be said that the task was well completed, and the feelings of the two became stronger after the separation and integration. I guess they finally got together.
