In 2036, Beichuan Middle School collaborated with a gaming company to allow students to play the trial version of the virtual game "Campus Adventure." Unexpectedly, the boy No.1, who ended up in the hospital after falling down the stairs, accidentally entered the game and began his journey of battling monsters without fully understanding what was happening. In the game, he reconnected with the class monitor Han Han, with whom he rarely interacted, and the cool male classmate Cheng Hongjie.

2036年，北川中学校方与游戏公司合作，让学生试玩虚拟游戏《玩转校园》测试版本。莫名从楼梯摔下而入院的少年诺一竟阴差阳错进入游戏，糊里糊涂就开始了打怪之旅。游戏里，他重新认识了原本极少交流的学霸班长韩涵与冷酷男同学程宏杰。
然而，诺一失忆了。他不记得自己进入过游戏，也不记得与好友应战的情景。同时，出现在背包里的优盘竟让他掉入陷阱……
这一切究竟有何关联？诺一又是否能找回失去的记忆？
