The Silent Sea

On a near-future Earth suffering from extreme desertification, draconian measures have been put in place for potable water rationing. Scientist Song Ji‑An (Bae Doona) joins a hand-picked team of elite personnel on a mission to the Moon. They are headed to an abandoned research facility, Balhae Station, where her sister died five years prior, after 117 personnel were killed in an incident. The circumstances surrounding the incident are secret. Their mission is to retrieve a mysterious and sensitive sample. The captain of the team, Han Yun‑Jae (Gong Yoo), is a soldier for the space agency. Lieutenant Ryu Tae‑seok (Lee Joon) of the Ministry of National Defense volunteers to be part of the crew. At the lunar facility, Song ascertains that the higher-ups have floated a bunch of half-truths and outright lies regarding the mission and the facility, and the nature of the accident that wiped out the staff. The sample turns out to consist of a new element that ostensibly looks like water, but multiplies like a virus when it comes in contact with living cells. The team is attacked by a violent superhuman girl on the space station, one who is immune to the effects of lunar water. Meanwhile, they must contend with the fact that some members of their own party may have ulterior motives that lead to betrayal.
