A Plagued Sea

While waiting for a train to Haewon, an isolated Korean seaside village, bodyguard Mu-young gets a disaster alert on her phone. TVs throughout the station report breaking news of a massive earthquake on the eastern coast. Despite the danger, Mu-young boards the train with her niece: she'd rather face the earthquake than leave the girl in her mother's care. That choice haunts her for the rest of her life.
