The storm is coming—literally. Netflix is gearing up to drop its latest Korean sci-fi disaster film, The Great Flood, featuring two of the platform’s favorite stars, Park Hae Soo and Kim Da Mi. Set to premiere on December 19, 2025, this film promises an emotional rollercoaster of survival, mystery, and sacrifice in the face of a world-ending deluge.
🌀 A Familiar Pair for Netflix Fans
Both leads are no strangers to Netflix audiences.
Park Hae Soo, often dubbed “Netflix’s golden actor,” stole hearts (and headlines) with his roles in Squid Game and Money Heist: Korea. Meanwhile, Kim Da Mi first captured international attention in Itaewon Class and later charmed viewers in Our Beloved Summer.
Now, the two return to the streaming giant together in The Great Flood — a film that could easily be one of Netflix’s most anticipated Korean releases of 2025.
💧 1. The Story: When the World Is Drowning
As the title suggests, The Great Flood tells the story of a massive flood that devastates Earth.
In the middle of this catastrophe, An Na (Kim Da Mi) and Hee Zo (Park Hae Soo) take refuge in a flooded apartment building in South Korea. As the water levels rise, survival becomes increasingly desperate — and secrets begin to surface.
There’s more to this disaster than meets the eye. Beneath the chaos lies a hidden truth about the flood itself and the mysterious bond that compels Hee Zo to protect An Na and her young son at all costs.
👩👦 2. Kim Da Mi Takes on Her First “Mother” Role
In a surprising transformation, Kim Da Mi plays a single mother for the first time in her career.
Known for her emotionally charged and versatile performances, Kim once again pushes her boundaries in The Great Flood. Her portrayal of a mother fighting for her child’s survival adds an intimate, human touch to the grand-scale disaster theme.
🌍 3. The Last Day on Earth
Netflix’s teaser trailer gives a haunting glimpse into humanity’s final hours.
Hee Zo — a member of a human resources task force — sets out on a mission to rescue An Na. But there’s a twist: on the last day of life on Earth, An Na might be the key to saving all of humanity.
The teaser hints at a mysterious rocket launch amid the flood — perhaps a desperate attempt to carry An Na, and the last hope of mankind, beyond the dying planet.
🎬 4. From the Director of Omniscient Reader
The film is written and directed by Kim Byung Woo, who also helmed the upcoming Omniscient Reader starring Ahn Hyo Seop and Lee Min Ho.
The Great Flood marks Kim’s second major project of 2025 — and his first venture into the disaster genre. Fans of his sharp storytelling and emotional depth can expect an intense mix of science fiction, suspense, and human drama.
📅 5. When to Watch The Great Flood
Mark your calendars: The Great Flood premieres December 19, 2025, exclusively on Netflix.
With its powerhouse cast, apocalyptic premise, and cinematic direction, this could easily become the year’s biggest Korean film on the platform.
🎥 Final Thoughts
The Great Flood looks like a rare blend of heart-pounding survival and emotional storytelling, backed by Netflix’s signature production scale. With Kim Da Mi and Park Hae Soo at the center of it all, expect nothing less than an unforgettable cinematic storm to close out 2025.
