Shen Yu (Shou) suspected that the cause of his mother's death was related to the illegal transactions of some pharmaceutical companies, so he was transferred to the Lin'an Criminal Investigation Detachment alone as the deputy captain. Together with Captain Su Heng (Gong) and other members of the Lin'an Criminal Investigation Detachment, they solved the case. Through a series of small cases, they finally found that Fenghai Pharmaceutical Group produced and sold drugs through illegal medical experiments, and his mother died as a result.
In the process of solving the case, the protagonists go from mutual dislike to mutual attraction. Gong is encouraged by Gong to grow in the level of solving crimes. With Gong's support, he is no longer alone and reconciles with his father and overthrows political opponents. They cooperate with each other and finally avenge the death of his mother.
Intention: Crime will eventually come to an end, and our side by side has no boundaries.
