Among the recruits who just joined the army, there was a rebellious teenager named Gao Gao, who was criticized by the company commander Cui Ming and the monitor Sun Jun because he didn't adapt to the life of the army. But Gao went his own way and ignored others, becoming a "barbed soldier". After the connection, he was assigned to a repair class in the mountains.
Cui Ming, the company commander, began to set up a mine-clearing team, ready to lead the team to the minefield. In the repair class, the recruits got to know the veteran Ram Raymond. Gradually, from the beginning of tit-for-tat, to mutual appreciation, and then to mutual cooperation to complete dangerous tasks such as chasing gangsters and saving lost girls, the spiritual identity and inheritance were completed.
LAM Raymond finally promised to teach a demining skill to higher education. Higher education has also completed the change of life belief in a difficult environment, and began to realize the truth of "serving the country as a soldier" and "serving whom". He was extremely loyal to the party and the country, studied hard and trained hard, and began to slowly change from a rebellious local youth to an excellent engineer with persistent beliefs.
