In 1937, Shanghai fell and war raged. Chen Ye, a doctor of psychology who returned from studying in Germany, was involved in the tide of the times before he could realize his academic ambitions. His mentor, the head of our party's underground organization in Shanghai, died heroically because of betrayal by a traitor.
When he was in danger, Chen Ye inherited his mentor's legacy, assumed the pseudonym "Dr. Chen", and opened a psychological clinic in the French Concession. His codename is "Illusionist". His weapons are no longer scalpels and stethoscopes, but micro-expressions, hypnosis and psychological profiling. He can see through the deepest lies and weave the most perfect deception.
On an isolated island full of dangers, while fighting wits and courage with the jackals, tigers and leopards of the Japanese Special High School and Wang Puppet No. 76, He quietly weaved a red intelligence network called the "Spider Web". He met the progressive female student "Chu Yue" who made his heart beat, but he never thought that behind this pure love, there was the most deadly murderous intention hidden.
When he discovered Chu Yue's true identity - Japan's ace agent "Yuki Sakura", his world collapsed. Love and faith, sincerity and disguise, how should he choose? In this game where people's hearts are the bet, who is the final winner? And who is the ultimate traitor code-named "Pluto" lurking in the deepest part of the organization?
