Lin Yi, 42, is a veteran investigator with the anti-corruption bureau in a major city. He appears stern and incorruptible, but in recent years he has privately helped several businessmen "handle" questionable evidence and accepted "thank-you payments" to cover the costs of his gravely ill wife and his son's international schooling. His wife has since passed away, and his 17-year-old son is preparing for the college entrance exams. Lin Yi has long comforted himself with the thought that he only needs to hold on for a few more years before he can leave it all behind.
