In Sector 7, an underwater oil field located south of Jeju Island, Hae-jun is working as a marine equipment manager on an oil prospecting ship called Eclipse. Joining the crew later is Jeong-man, a former colleague of Hae-jun's father, assigned to Eclipse as captain. Though his job is to oversee the withdrawal of the ship, he suggests conducting some drilling one last time.

Why it matters

A claustrophobic dive into deep-sea terror where industrial ambition meets something monstrous beneath the waves.

  • A standout in Korean creature horror, blending oceanic isolation with eco-anxiety undercurrents.
  • Practical effects bring the deep-sea beast to grotesque, tangible life—no CGI overreach here.
  • The cramped, industrial setting amps tension, recalling classics like The Thing’s Antarctic station vibe.
  • For fans of atmospheric, creature-driven horror that critiques humanity’s reckless exploitation of nature.
