Lin Zhiwang is locked up in a psychiatric hospital just for saying he saw a shadow behind his doctor. He desperately collects bookmarks and dirt as evidence to prove he isn't crazy, but no one believes him. The more medication he takes, the more real his hallucinations become. In the end, when he puts a finger to his lips and shushes the empty air, everyone says, "Look, he's finally cured."
