Deng Xiaoping (Xu Guanying) has been upright and helpful since childhood, and his wish is to be a good policeman when he grows up. Helplessly, because of his short stature and natural color blindness, he was turned away from the police station, so he had to go to the security company as a security guard. Zhou Shichang (Xu Guanwen), the head of security, is an old Youtiao, who is mean and afraid of death. Subordinate Sam (Xu Guanjie is acted the role of) early in the morning to see him not pleasing to the eye, but there is no place to apply for injustice. This time, the crown prince of the company came back from studying abroad and pretended to be a security guard to investigate the situation of the company. Soon Sam and Xiaolong were promoted because of their excellent work, while Zhou Shichang was stripped of his position of supervisor and demoted. He will be able to retire in a few months. Will he put up with this bad breath for his pension or will he have another plan?
