Four freshmen live in dormitory 412 of Jiangcheng University.
Lin Chaonan, the underworld prince, came to school concealing his identity and just wanted to be an ordinary person. Zhou Haiming, a Sanda master from Shaolin Temple, looks carefree, but there are old injuries on his wrists. Chen Jinnan, the son of a dock boss in Wenzhou City, drove a Land Rover to check in, with extraordinary skills hidden under the logo all over his body. Shen Yingchuan, whose schedule was as precise as a clock, had been waiting in this dormitory for a year, and no one knew who he was waiting for.
Three years ago, a sum of 37 million in black money attracted various forces to the door of this dormitory. Some people broke in in the middle of the night and waved baseball bats, some stood outside the door at two o'clock in the morning and listened, and some set up spies in the school.
Four young people, each with their own secrets, went from testing each other to standing side by side. When their opponents in the dark finally revealed their trump cards, they decided to play this game themselves.
