Sea Fog Trailer (2014)

Trailer for Sea Fog, also known as Haemoo.

A high-seas adventure with substance and heart, Haemoo is exactly why Hollywood is beating a path to South Korea's door. This gripping drama offers the tense, steady build of a film like Jaws — although in this case the threat is human.

Kang (Kim Yoon-seok) is captain of a fishing boat crewed by rough men who are used to the harsh realities of life at sea. Their regular fishing runs net them only a meagre income for their families back home, so when a more lucrative opportunity comes up, Kang grabs it. The job: smuggle a group of ethnic Koreans leaving China for new lives in South Korea. It's risky — and illegal — but offers the prospect of bricks of cash. Desperate migrants or dead fish: Kang doesn't care what he brings back to port if it means money.

His crew is a more complex mix of individuals, including Dong-sik (Park Yu-chun), an inexperienced young sailor. He strikes up a romance with a migrant named Hong-mae (Han Ye-ri), giving her a "first class" hiding spot in the engine room while the others are left in more dangerous circumstances.

Haemoo is based on actual events, which gives a sharp dimension to its story of crew members scheming, battling, and ready to exploit their human cargo.
