Sharpshooter Xiang Qian meets top student Qin Feng. The two clash nonstop, from dorm brawls to shooting range duels, even competing over cafeteria meals: they sneak chili sauce into each other's food to make them tear up, and their midnight streaking is once live-streamed to the whole campus by a drone. Soon, Sanda martial arts queen Guan Yue and tactical whiz Ye Yu get dragged into the chaos. The four go from pranking and bickering to trusting each other with their lives, ultimately taking bullets for one another at a drug raid site.
