In the fictional country at the border of Europe and Asia, a five-member team was ordered to face danger. They encountered many pitfalls and farce, and experienced recruits joining the army, border chaos, core cases and the ultimate life and death battle. In the alternation of humor and tension, there are both cannon fodder-like mistakes and instinctive breakthroughs. Along the way, they established comradeship through laughter and tears, faced beliefs and responsibilities, and grew and transformed under the flames of war. In the end, they used their own methods to fight against the conspiracy, prevent the war from getting out of control, and protect their original intention and military soul.
