Sector 7

“Something awaits them 8,000 feet under the sea…”

A threat lies beneath Sector 7, an oil field under the sea south of Jeju Island, and the crew of the drill ship Eclipse is slow to learn it. Cha Hae-joon (Ha Ji-won), the ship's marine equipment manager, is winding down the crew's work when the new captain, Lee Jeong-man (Ahn Sung-ki), a former colleague of her father's, asks for one more round of drilling. Kim Ji-hoon holds Hae-joon in close frame on the Eclipse, the crew around her, the drill still turning.
