Every year, Six Mile Island has a seasonal shutdown for serious weather. This year, the forecast is calling for the storm of a century, so most of the population has agreed to an evacuation in order to more safely ride out the storm on the mainland. When a child goes missing on the cusp of the oceanic storm, a select few inhabitants are left behind to perform a frantic search. Little do they know that the ocean is bringing more than a storm to Six Mile... An ancient species hungers from the sea.
