All the psychiatric cases described here are based on real events.
You might say this is impossible. But I insist: everything is possible. Because all of this is the result of the human mind. And of human madness…
Chen Putian and Yang Ke, who work in a clinic in Nanning, aren’t just psychiatrists. They act as detectives, investigating cases related to mental disorders. Although they often argue, their cooperation allows them to successfully solve strange and dangerous riddles while also making accurate diagnoses. The clinic sends them to a school psychological assistance center, where a high school student tragically died. However, her friend is sure she’s alive and claims to see her. During a conversation with this student, the psychiatrist-detectives learn that she has “a goldfish memory”: she forgets them after a while and can’t retain current events. Moreover, although it’s now October, the girl is still living in May—more precisely, in a single day of May… A complicated case. But ahead of them is something even worse: a secret… of a dead woman’s body locked away in a corridor on the minus second floor of their clinic.
