Four freshmen live in Room 412 at Jiangcheng University.
Lin Chaonan is an underworld heir who has concealed his identity to attend university. All he wants is to live like an ordinary person. Zhou Haiming is a sanda fighter who came from Shaolin Temple. He seems carefree and boisterous, but an old injury marks his wrist. Chen Jinnan is the son of a big shot at the docks in Wenzhou. He arrives in a Land Rover, covered in designer logos, with a formidable fighter’s skills beneath the flashy exterior. Shen Yingchuan keeps to a schedule as precise as clockwork. He has been waiting in this dorm for a year, and no one knows who he is waiting for.
Three years ago, 37 million in illicit funds drew various factions to the door of this dorm. Someone broke in at night wielding a baseball bat, someone stood outside at two in the morning listening in, and someone planted spies around the campus.
The four young men, each with secrets of their own, go from testing one another to standing side by side. When their hidden enemy finally reveals their hand, they decide to play the game themselves.
