"Extreme Occupations" tells the story of a narcotics officer at the Mapo police station in Seoul who is always half a step behind in his promotion. At the moment of crisis when the narcotics unit under his leadership is facing disbandment, and even the position of a small team leader will be lost, thinking that he may have to work as an inside man under his juniors in the future, the senior team leader makes a major decision to pour out his pension and buy the dying fried chicken store across the street from the base of the drug trafficking organization to lurk around and wait for the chance to kill them all. Several members of the narcotics team have distinct personalities, and although they aren't great at their jobs, the small team is very tight-knit. In order to accomplish their mission, the five cops who switched identities at the fried chicken store all found new identities that suited them. Based on the principle of "doing one thing and loving another", they run the fried chicken restaurant with great success. However, a bigger problem arises: they are too busy to solve crimes. They also took measures such as increasing the price of fried chicken and limiting the supply. However, as a result of the media exposure, the fried chicken store business is in the doldrums, and the drug lords have taken advantage of the opportunity to get in on the action, using the takeaway from the fried chicken store to start a drug trafficking business.
The story of China's Lobster Cops is basically similar to this one, except that it's a lobster instead of fried chicken. The unreliable narcotics squad of chatterbox Du Yufei, semi-retired Uncle Neng, marriage-hating Flora, and newcomer Chen Kasa, in order to keep a closer eye on the drug dealers, take over the lobster store next door. But business is booming, and the team makes a series of ridiculous jokes as they search for clues while running the lobster store, and there's a bigger conspiracy surrounding the lobster store.
The storyline of the two films is basically the same, and the actors are basically acting, but it has produced different box office performance, which is really should be the Chinese filmmakers reflect.
