Submersion is a South Korean action and science fictionfilm directed by Kim Byung-woo, starring Kim Da-mi and Park Hae-soo. This apocalyptic thriller plunges the viewer into a world submerged by an unprecedented flood, where survival becomes the only priority. The film will be available on Netflix from December 19, 2025.
As a global catastrophe causes the waters to rise to apocalyptic levels, a building becomes the last refuge for a small group of survivors. Amidst the chaos, a woman and a man join forces to save a child trapped in an apartment that is being engulfed by the rising waters. Between the race against time, despair, and rediscovered humanity, Submersion depicts a race against death in a world in agony.
Directed by Kim Byung-woo (The Terror Live), the film follows in the tradition of major Korean genre productions, combining tension, emotion, and spectacular aesthetics. Kim Da-mi and Park Hae-soo deliver intense performances in a water-bound closed setting where physical and moral survival merge.
With its post-apocalyptic settings and immersive visual effects, Submersion explores both the consequences of an ecological disaster and human resilience in the face of the world's collapse. The film is aimed at fans of disaster thrillers and realistic survival stories, in the vein of Train to Busan or The Wandering Earth.
