Lin Yu leads a special forces team and is ordered to carry out a number of crisis missions, from border drug seizures to overseas rescues. They face life and death with a smile every step of the way in dangerous situations. The team members grow up individually, experience trust tests, friendship separations and undercurrents, and emotional undercurrents, and compete with the villain Vera in a battle of wits and courage under the conflict of multinational forces and interests. Volume 1 focuses on the formation of the team and its initial trials, Volume 2 describes the team's betrayal and shaken mission, and Volume 3 faces life and death decisions and final resistance, always using humor to intersperse dangers and show the true qualities of the special forces. In the end, the team worked together to complete the mission, smile on their way home, and complete growth and redemption.
