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.

二十世纪七十年代，三个完全不同的年轻人在部队这所革命的大熔炉里：一个一心要当叱咤风云的战斗英雄、一个发誓要在部队出人头地往上爬、一个则是浑浑噩噩地被当了兵。三人在同一天走进同一座军营，吃同样的饭，叠同样的被子，走同样的正步，却因为性格、动机、世界观的差异，彼此之间产生了各样的矛盾与冲突。在经历了一系列的挫折与磨练之后，他们完成了从普通老百姓到优秀军人的转变，练就了铁打的骨头，结下了生死的战友情谊，更铸成了为祖国、为人民一切行动听指挥、甘愿牺牲奉献的钢铁信念。
