During his two-year military career, a tactical mistake made Lin Yan burdened with guilt and self-blame. He quietly took off his beloved camouflage uniform and hid in a self-isolated corner in the name of dropping out of school. When he re-entered the campus of Ningzhou University, the whistle of the retraining military training was like a key, unexpectedly opening up the dusty memories - the slogans at the training ground, the smiles of his comrades, Chen Yang's injured appearance, the past that had been deliberately buried came to mind again.
He is the "camouflage alien" on campus. His tall and straight figure and military qualities engraved in his bones are incompatible with the youthful and careless surroundings. He is taciturn and builds a high wall to isolate himself from everything, but inadvertently, he is quietly approached by the gentle and firm Su Xiaoran and his enthusiastic and cheerful roommate Wang Hao. The breakdown and confession on the military training ground allowed him to take off his disguise for the first time and let others know the secrets and guilt in his heart.
A call from the captain, the expectations of his comrades, and a belated gathering of his comrades became an opportunity for him to reconcile with the past. Returning to the camp, the hugs with Chen Yang, the teasing of the brothers, and the relief of the captain made him finally understand that true comradeship will never fade due to a mistake, and the regrets in those camouflage years will eventually be cared for and tolerated and turned into warm residual warmth.
From self-imprisonment to calm relief, from being alone to being accompanied by others, Lin Yan found his lost self in the fireworks of the campus and the old days of the military camp. The residual warmth of camouflage not only heals the pain of the past, but also illuminates the road to the future - here is the brotherhood of fighting side by side, the love of sons and daughters who walk together tenderly, and the courage and responsibility to face life head-on after suffering.
