In the prosperous and mixed coastal city, Lin Yu is a retired special forces soldier. Tired of the bloody life, he chose to remain anonymous in the city and run a small security company. By chance, he met Su Yao, a beautiful and independent fashion designer. The two were quickly attracted to each other and began a sweet relationship. However, the peaceful life did not last long.
Su Yao's design company was involved in a business conspiracy. In order to obtain huge profits, the company boss colluded with dark forces and tried to steal the design plans of internationally renowned brands. Su Yao accidentally discovered this secret and became a thorn in their side. The dark forces began to launch a series of threats and pursuit against Su Yao.
After Lin Yu learned about his girlfriend's dangerous situation, he decided to return to the world. With his excellent military skills and calm mind, he rescued Su Yao from danger time and time again. In the process, Lin Yu not only had to face vicious gangsters, but also had to deal with the police, because the police once misidentified Lin Yu as a criminal suspect when investigating the case.
As the investigation deepened, Lin Yu discovered that there was a bigger secret hidden behind this business conspiracy, involving international criminal organizations. He and Su Yao supported each other in difficulties, and their love became stronger in the hardships. In the end, Lin Yu teamed up with the police to successfully smash the criminal organization's conspiracy and protect Su Yao and her company, and the two also ushered in a happy ending.
