In the 1970s, three completely different young people were in the revolutionary melting pot of the army: one was determined to be a fighting hero, the other vowed to rise to the top of the army, and the other was a scumbag soldier. The three of them walked into the same barracks on the same day, ate the same meal, made the same quilt, and walked the same goose steps, but because of their differences in personality, motivation, and worldview, they had various conflicts with each other.
