Could it have gotten worse for the Busan prison detail extraditing four dozen hardcases out of Manila on a cargo ship to have mercenaries assist the convicts with an armed and bloody breakout attempt? It could and did, as the tumult unleashed a indestructible, barely human berserker hidden in the vessel's hold-and he isn't taking sides. Jaw-droppingly violent sci-fi actioner stars Seo In-Guk, Jang Dong-Yoon, Jung So-Min, Sung Dong-Il, Choi Gwi-Hwa. 122 min. Widescreen; Soundtrack: Korean; Subtitles: English. In Korean with English subtitles.
