Netflix’s Korean sci-fi disaster thriller The Great Flood (original title: 대홍수) drops December 19, 2025, and it’s a gut-wrenching race against time that blends apocalyptic spectacle with intimate human drama. Directed by Kim Byung-woo and anchored by Kim Da-mi and Park Hae-soo, this isn’t just another apocalypse story; it’s a mother’s nightmare playing out in real time.
Trapped When Everything Falls Apart
Picture Earth’s final hours. An asteroid collision triggers planetary flooding, and in one doomed apartment tower, researcher An-na finds herself and her son facing rising water with every passing minute. Then a stranger arrives, a security operative with an agenda that shatters An-na’s world further: she’s the key to birthing humanity 2.0, but saving mankind means abandoning her child.
Streaming December 19, 2025, on Netflix.
The film debuted at the Busan International Film Festival in September 2025, earning recognition for its emotional weight paired with stunning visual destruction.
Most disaster films trade in spectacle—massive waves, crumbling cities, heroic last stands. The Great Flood takes the opposite approach, trapping viewers in a suffocating space with a mother forced into an impossible moral equation.
Who Should Watch
Fans of Train to Busan, The Wandering Earth, or The Silent Sea will recognize the blend of human vulnerability against world-ending odds, but The Great Flood leans deeper into moral ambiguity than pure action. Kim Da-mi and Park Hae-soo carry the weight of impossible choices without melodrama.
