The Great Flood is Netflix’s latest South Korean disaster film, delivering a gripping mix of large-scale catastrophe and deeply emotional human drama. Released globally in December 2025, the movie reinforces Netflix’s dominance in Korean storytelling while tapping into the global appetite for high-stakes survival thrillers.
Set in a near-future Seoul on the brink of collapse, The Great Flood explores how ordinary people respond when nature, technology, and fate collide. With standout performances by Kim Da-mi and Park Hae-soo, the film blends spectacle with intimacy, making it one of Netflix Korea’s most ambitious releases to date.
What Is The Great Flood About?
At the heart of The Great Flood is a terrifying scenario: a massive tsunami triggered by an asteroid-related event crashes into Seoul, overwhelming the city’s infrastructure and plunging millions into chaos.
Kim Da-mi stars as An-na, a scientist and single mother who finds herself trapped in a high-rise building with her young son as floodwaters rise at an unstoppable pace. As panic spreads across the city, the film depicts scenes of evacuation failures, looting, and social breakdown—mirroring real-world disaster anxieties.
During a desperate escape attempt, An-na becomes separated from her child, setting off an emotional survival journey that drives the film’s narrative tension.
Kim Da-mi and Park Hae-soo Lead a Powerful Cast
One of the strongest elements of The Great Flood is its casting.
Kim Da-mi as An-na
Kim Da-mi delivers a raw and emotionally grounded performance as a mother torn between scientific rationality and primal survival instincts. Her portrayal captures fear, resilience, and sacrifice, anchoring the film’s most intense moments.
Park Hae-soo as the Mysterious Survivor
Park Hae-soo plays a quiet, enigmatic man An-na encounters amid the devastation. His character’s unclear motivations introduce a psychological edge, forcing viewers to question trust and morality when survival is at stake.
Their evolving dynamic adds emotional depth, elevating The Great Flood beyond a conventional disaster spectacle.
Direction, Visuals, and Disaster Scale
Directed by Kim Byung-woo, known for blending realism with tension, The Great Flood balances massive CGI-driven destruction with grounded storytelling.
Key highlights include:
- Realistic flood simulations engulfing Seoul landmarks
