The Prison

“Rule The Outside From Within.”

Song Yoo-gun (Kim Rae-won), a former cop jailed for corruption, just wants to serve his time and get out. Then he finds that the whole penitentiary answers to one inmate, Jung Ik-ho (Han Suk-kyu), a kingpin whose men commit perfect crimes outside by night. Na Hyun keeps Yoo-gun inside those walls, where refusing Ik-ho costs as much as joining him.
