"The Great Flood" is a South Korean science fiction, action, and survival film that premiered globally on Netflix at the end of 2025. Directed by Kim Byung-woo, known for his skill in handling suspense in confined spaces (as in "The Terror Live"), it became one of the most-watched titles on the platform within a few days, according to the Argentine News Agency.
The plot is set on the last day of Earth. An apocalyptic flood has submerged almost the entire planet under water. The film does not focus on the global disaster, but on a desperate struggle for survival within a very specific environment: an apartment that is flooding in a high-rise building.
The protagonists and the conflict Anna (Kim Da-mi): An artificial intelligence expert who becomes trapped in her apartment as the water level rises uncontrollably. Hee-jo (Park Hae-soo): A member of a security team who tries to rescue Anna amidst the chaos.
As the water rises and the building's structure fails, the film reveals that the rescue is not so simple. Secrets about the characters' pasts and the true reason why Anna is so important to be saved intertwine as the world comes to an end.
What makes it different? Claustrophobic suspense: Despite the disaster being a "great flood" (an open space), the film feels oppressive because it takes place in hallways, stairs, and rooms that become deadly traps. Visual effects: The production stands out for the realism of the water and the destruction of South Korean infrastructure, something Netflix has enhanced in its high-budget productions in Seoul. Ethical dilemmas: Beyond the action, it explores themes such as artificial intelligence, memory, and to what extent it is worth surviving when nothing is left outside.
