SINNER
자필
“Help me, before it's too late.”
Synopsis
When the ostensibly unblemished prosecutor Kim Seokgyu is nominated for Minister of Justice, the opposition party raises questions about the 1994 "Migeum Arson-Murder Case." They allege that he conducted a coercive investigation against the illiterate suspect Hong Sunhwa and sought the death penalty; however, the crisis passes when a letter left by her comes to light. Yet, after belatedly reading her plea for her innocence to be conveyed to her son Eunsu, Seokgyu begins to reinvestigate the closed case. A prosecutor who once sought justice only within documents and courtroom walls confronts the truths he had overlooked through the voices of those involved.
