Shen Zhao, a general's concubine, was framed by her aunt and her family was wrongfully exterminated. She was forced to disguise herself as a man and join the army. She was promoted from a corps commander to a general on the edge of the town by virtue of her military strategy and martial arts skills. However, in the confrontation with Xiao Chengyan, the enemy's king of Zhenbei, she fell into the dilemma of family and country justice and deep-rooted love. From sworn enemies on the battlefield to secret love, the two went through intelligence traps, suspicions about killing prisoners, and drug and wine confrontations. In the end, in the decisive battle between the two countries, they swore on a broken sword and used a lifetime of sadomasochism to interpret the oath of "live up to the red makeup and live up to the mountains and rivers." The highlight focuses on the heroine's brilliant moments when she outwits the enemy, kills the framer, and defeats the strong with the weak. The sadomasochism runs through the ultimate pull of "love but dare not admit" and "believe but not trust".
