Hae-won (Seong-won Ji) is a woman on the edge: a series of incidents at work earn her a forced “vacation,” but when she travels to a remote island from a childhood visit, at the urgent request of her friend Kim Bok-nam (Yeong-hie Seo), she has no idea what devils of the past are waiting.
Moo-do Island is an unpleasant place to visit, and you definitely don’t want to live there. Bok-nam is crumbling under a weight of violence, sexual menace, and fear – with no means of escaping her tormentors. The vengeful rage that waits inside her is growing, and her sanity shredding. If Hae-won can’t help her escape, she may have to take matters into her own hands, once and for all.
