One morning in December, Kyungha is called to her friend Inseon’s hospital bedside. Airlifted to Seoul for an operation following a wood-chopping accident, Inseon is bedridden and begs Kyungha to take the first plane to her home on Jeju Island to feed her pet bird, who will quickly die unless it receives food. Unfortunately, as Kyungha arrives a snowstorm hits. Lost in a world of snow, she begins to wonder if she will arrive in time to save the bird – or even survive the terrible cold that envelops her with every step. But she doesn’t yet suspect the darkness which awaits her at her friend’s house. There, the long-buried story of Inseon’s family surges into light, in dreams and memories passed from mother to daughter, and in a painstakingly assembled archive, documenting the terrible massacre seventy years before that saw 30,000 Jeju civilians murdered.
