Two of Korea’s biggest stars, Hwang Jung-min and Gang Dong-won, team up for a twisty prison-set thriller that channels The Shawshank Redemption before veering off into more political territory. Fresh from Veteran, Hwang is the violent prosecutor of the title who is framed for the death of a witness in his care. Abandoned by his fellow prosecutors, Hwang plies his skill to rise to the top of the food chain behind bars and when a young swindler (Gang), who may have information that could exonerate him, appears before him, he takes his case and grooms him for release.
