Are you looking for a high-stakes dystopian drama with a twisty plot? Netflix‘s latest South Korean movie, The Great Flood, is currently storming the charts – and it promises to keep viewers hooked from start to finish.

Set in Seoul in the near future, the film charts the threat of an impending tsunami on single mother An-na and her son Za-in, who become separated from each other. When An-na meets a mysterious man who claims he wants to help, little does she know that his motives are far from altruistic.

I love a disaster thriller, and The Great Flood is sure to scratch the itch for fans of films like The Day After Tomorrow, World War Z and The Wave. Directed by award-winning filmmaker Kim Byung-woo (The Terror Live), the movie stars Squid Game‘s Park Hae-soo, alongside Kim Da-mi (Itaewon Class), and is currently ranking as the most-watched film worldwide on the streamer.

Kim Byung-woo is known for grounding high-concept thrillers in tight, claustrophobic settings, as seen in The Terror Live, and The Great Flood follows the same approach by keeping much of the tension focused on a single building rather than large-scale spectacle.
