Chen Feng is a psychiatrist with an in-depth knowledge of microexpressions and behavioral psychology. After treating an eccentric patient who claims that a character has taken over his body, he discovers that he has been drawn into an incomprehensible supernatural system: the Mask System. Wearing different “identity masks” grants him corresponding abilities, but at the cost of eroding his sense of self. When his first patient dies mysteriously, leaving behind nothing but a blank mask, Chen Feng is forced to put it on and embark on a desperate path of “pretending to be someone else in order to survive.”
