Su Yan, a special soldier code-named Spider, unfortunately died in a joint military-police operation that crossed the border. When he woke up, he became a policewoman with the same name in Nancheng City who hadn't passed the internship period... The old detectives are the most impatient to take interns, especially the kind of female interns with good family conditions and charming, but they are assigned to one of their teams this year... On this day, the men of the Criminal Investigation Detachment gathered together to ask questions. Jiang Li: Captain Jiang, what do you like about Su Yan? Picture her as strong as an ox and can tear a tiger with her hands? Picture her capable of shooting you in the head from a thousand meters away? Picture her flying a plane with one hand and driving with her feet? Jiang Li (smiling with honey): vulgar. Then he stopped talking, just when everyone thought he would end this topic, he suddenly said: I want her to open a durian with one hand, and chop a watermelon with her bare hands. Lost!... Su Yan: I swear to obey the leadership of the country, serve the people wholeheartedly, not be afraid of sacrifice, and defend the motherland to the death! Jiang Li: I swear to be loyal to the country, serve the people, enforce the law fairly, and defend the motherland to the death!
