Johannes Bah Kuhnke (Force Majeure, Real Humans) plays the lead role in this thriller directed by debutant Ben Parker. A nuclear drone has crashed into the water off the coast of North Korea. Three special ops and an environmental scientist are commissioned to find and defuse the drone, but when an explosion causes a pressure wave that hits their submarine they are caught in the dark ocean. The submarine begins to take on water and there seems to be no rescue in sight. Now they must both defuse the drone and get up to the surface alive.
