Plot overview — short and spoiler‑aware
When a colossal tsunami sweeps into Seoul, water pours into buildings and streets with terrifying speed. With evacuation routes cut off and chaos spreading, An‑na realizes the only way to survive in her third‑floor apartment is to move upward — into a taller building and through a city engulfed by panic, looting and confusion.
Separated from her son amid the chaos, An‑na is rescued by Hee‑jo. Together they search for Za‑in, but Hee‑jo’s true reasons for helping are not immediately clear. As their journey unfolds, An‑na discovers choices she must make that may determine not only her family’s fate but the wider consequences of an extinction‑level event.
