What if natural disasters were alien smokescreens designed to mask something far more ominous? When a hurricane threatens a small town in Florida, park ranger Russell Poole's young daughter is the only one to see small lights floating towards the water, seemingly unaffected by the vicious winds. At the time, he thinks nothing of her claim, but begins to suspect something may be amiss when his missing ex-wife is found, with no memory of what happened during the storm. In the aftermath of the storm, water-based creatures infiltrate the town and take over the bodies of the town's residents through a cloning process.
