Ling Feng, the new starting boss of the civil service examination institution, has superb business skills and an outstanding reputation in the industry. Unexpectedly, his partner Gao Han used his influence to secretly collect high bribes from students. After realizing this, Ling Feng immediately broke with him. Resentful, Gao Han started another Navigator training institution, competed with Xin Qihang everywhere, and constantly poached students. His girlfriend Cheng Linlin disguised herself as a student to sneak into Xin Qihang, intending to steal course materials, make trouble secretly, and attempt to lower the institution's landing rate. Ling Feng's son Ling Yi had long seen through Cheng Linlin's disguise. Facing the other party's malicious sabotage, Ling Feng united students to cleverly fight back, and grasped conclusive evidence of Cheng Linlin stealing materials.
