A Hard Day (Blu-ray)

Driving back from his mothers funeral, homicide detective Gun-soo (Lee Sun-kyun) runs over a man in a dark rural street. In a moment of desperation, he dumps the body in a coffin alongside his mother. The disappearance of his accident victim is investigated by a colleague, and, making matters worse, a witness steps forward, a detective named Park (Cho Jin-woong). Parks motives are less than savory, and he begins issuing threats that become more vicious and hit closer to home. Eventually Gun-soo decides to face Park head-on once and for all.
