The Great Flood

Synopsis

An-na wakes to an ordinary morning with her six-year-old son, Ja-in. The boy looks out the window and cheerfully announces, "There's a swimming pool outside!" Within hours, Seoul becomes a grave swallowed by the ocean. The flood, triggered by an asteroid collision, is not merely a threat to Korea—it's a global catastrophe. An-na is an AI researcher, making her a candidate for government evacuation. But instead of boarding the helicopter, she dives back into the dark corridors where she lost her son. Again. And again. Because this flood is not only water; it is grief, memory, and the agony of reliving the same wound. The numbers on An-na's T-shirt change: 21,347 becomes 21,348. Is Ja-in real, or part of a simulation? You never know when the loop will finally break her. The film traps you inside the cycle with her.
