A New Korean Film Takes Netflix by Storm
Released globally on December 19, 2025, the film has held the top spot on Netflix’s non English movies chart for multiple weeks, making it a standout among international titles.
What The Great Flood Is About
The Great Flood (대홍수) is a 2025 South Korean science fiction disaster film directed by Kim Byung-woo and starring Kim Da-mi and Park Hae-soo both familiar faces well-regarded for their compelling performances in dramatic roles.
The story begins with An-na (Kim Da-mi), an artificial intelligence (AI) researcher and single mother. On a seemingly ordinary morning, she wakes up to find her city and the world drowning under an unprecedented flood caused by environmental catastrophe and global shifts. Trapped in a towering apartment building with her young son Ja-in, An-na must navigate rising waters and crumbling structures in a desperate bid for survival.
However, the film doesn’t end as a typical disaster survival story. Midway, the narrative introduces a major science fiction twist involving AI research, simulations, and humanity’s last-ditch effort to preserve human consciousness as the world faces annihilation.
Plot Highlights (Non-Spoiler)
- Survival horror: The first half focuses on An-na and Ja-in struggling to stay alive as floodwaters engulf their apartment.
- Sci-fi expansion: As the crisis escalates, government agencies and scientists reveal deeper layers of the catastrophe including secret AI development projects tied to An-na’s past work.
- Emotional core: At its heart, the film is about a mother’s relentless determination to protect her child while confronting the traumas of loss, survival, and human purpose.
This mix of genres from intense disaster sequences to philosophical sci-fi is bold, but also part of what has made the film a topic of debate among viewers.
