At the end of the Anti-Japanese War, under the call of "100,000 students, 100,000 soldiers", Zhicheng Cai, the fourth young master of Cai's family, who was born in Zunyi, came to report despite his father's stop.

Join the army. Cai's father bribed his son to join the army, but Zhicheng Cai changed his mind and joined the newly formed paratroopers of the Kuomintang. Later, Zhicheng Cai's fiancee, Ye Lingfeng, died in the army. Tang Bicheng, his most respected senior, betrayed Japanese spies and framed paratroopers. Zhicheng Cai is facing the test of emotion and faith. Zhicheng Cai's first paratroopers regiment, led by its captain Shao Yue, bombed the Shenhe Bridge, seized the legal field, rescued the paratroopers commander Meng, recovered the land and raided Hengyang Airport. After repeated life-and-death battles with the Japanese army, it gradually became a mature elite team. But at the same time, many comrades who fought alongside Zhicheng Cai, such as Xi Shaoyue and Luo Dayan, also died in the cruel War of Resistance against Japanese Aggression. Zhicheng Cai gradually saw the corruption and selflessness of the Kuomintang, and finally, inspired by Meng Xue, an underground member of the Chinese Communist Party, launched an uprising and led the first paratroopers to the real light.
