在城乡结合部的八里河派出所迎来了四名新人实习警员，分别是李大为、夏洁、杨树和赵继伟。八里河派出所的所长王守一是通过努力争取才争取来了四个实习警员。在新人报到的第一天，只有赵继伟和夏洁出现在了派出所按时报到。杨树和赵继伟却不见踪影。新人报到的第一天就迟到，这让王守一十分的头疼，为了欢迎这4个新人，还为他们专门准备了一场欢迎仪式，连宋局长都会出现在仪式上欢迎他们。这个时候却不见另外两个新人的影子，这就让王守一犯了难。与此同时，老民警陈新城接到报警出外勤，却在案发地碰到了原本应该报到的李大为。李大为在公交车上见义勇为抓到了人贩子，说自己是警员，但是却没有警员证。李大为最后和陈新城一起坐着警车回到了所里报到，作为一个新人警员，第一次报道就给大家带来个惊喜。新人杨树居然和宋局长坐着同一辆车来到了所里

The Balihe Police Station in the urban-rural fringe area welcomed four new trainee police officers, namely Li Dawei, Xia Jie, Yang Shu and Zhao Jiwei. Wang Shouyi, director of the Balihe Police Station, managed to win four trainee police officers through hard work. On the first day of the newcomers' registration, only Zhao Jiwei and Xia Jie showed up at the police station to report on time. Yang Shu and Zhao Jiwei were nowhere to be seen. The newcomers were late on the first day of registration, which caused Wang Shouyi a lot of headaches. In order to welcome the four newcomers, a welcome ceremony was specially prepared for them. Even Director Song would appear at the ceremony to welcome them. At this time, there were no signs of the other two newcomers, which made Wang Shouyi face a difficult situation. At the same time, Chen Xincheng, a veteran policeman, was called to the field and ran into Li Dawei who was supposed to report at the scene of the crime. Li Dawei bravely caught the trafficker on the bus, saying that he was a police officer, but he did not have a police officer certificate. In the end, Li Dawei and Chen Xincheng returned to the police station to report. As a new police officer, his first report brought a surprise to everyone. The newcomer Yang Shu came to the office in the same car as Director Song
