India, Dec. 21 -- The Great Flood, a South Korean sci-fi disaster movie directed by Kim Byung-woo, is now streaming on Netflix. Instead of being just a flood survival story, the film mixes big destruction with science fiction and puzzle-style storytelling.

The story follows An-na, played by Kim Da-mi, a scientist and single mother, and her young son Ja-in, when sudden flooding hits their tall apartment building.

According to Decider, midway through the film, the narrative shifts. An-na is revealed to be working in a secret AI laboratory, and a security agent named Son Hee-jo (Park Hae-soo) explains that an asteroid has struck Antarctica, threatening the future of humanity. From here, the movie leans heavily into science fiction.
