The Chamber (2016)

When a special ops unit commandeer a submersible to locate a mysterious item at the bottom of the Yellow Sea, the pilot of the sub (Johannes Bah Kuhnke, Force Majeure) is forced to navigate into dangerous, North Korean waters. When an explosion causes the sub to overturn and take on water, it becomes clear that there won't be any rescue and not all of them are going to escape. The Chamber also features a soundtrack by James Dean Bradfield (Manic Street Preachers) and stars Charlotte Salt (The Musketeers), James McArdle (Star Wars: The Force Awakens), and Elliot Levey (The Lady in the Van).
