From Su-chang Kong, the director of R-Point, comes a similarly themed Korean film that is part murder-mystery part horror-story. Also known as GP506 the film follows an army platoon headed by a military investigator as they are dispatched overnight to re-establish contact with the platoon stationed at Guard Post 506. On arrival they discover the aftermath of a gruesome bloodbath and one lonely survivor who they hope can provide the answer to the mystery behind the massacre.
