Siren (Sairen)
A writer and her two children move to a remote island, greeted by a dire warning from neighbors: "Don't go out when the sirens sound." At first they ignore it, until the sirens actually wail into the night—followed by screams and shadows peeking out of the darkness. Slowly, they realize that this island holds terrible rituals that outsiders should not know about. When his son disappears, the father must choose: break the rules or lose them forever. What is really hiding behind that siren sound?
