A supernatural horror thriller built on isolation, forbidden rules, and creeping dread, where a family's safety depends on obeying an ominous warning.

A writer moves to a remote island with his daughter and young son. After settling into their new home, a neighbor arrives to welcome them and give them a breakdown of the local rules; most important: do not go outside when the island's siren starts wailing.
