There is an unwritten rule in Hartford High School: All senior students must live in the dorm and study together for better exam results. They are even requested to give away their phones. However, the timid dorm manager Zeng Bao Qian is not able to handle these students at all. Two other teachers can’t stand his timid personality and decide to transform Zeng. The athletic student Gorilla performs poorly in his studies and even tries to cheat. Zeng uses his career as a bet with the principal and promises Gorilla can improve significantly under his instructions. Unfortunately, Gorilla isn’t able to reach the target, no matter how hard he tries. Zeng feels defeated and quits, but students appeal to the principal to keep him. Will Zeng accompany these students to the finish line?
