In the aftermath of a hurricane, a Florida Park Ranger and his family deal with strange occurrences, including luminescent creatures in the water and people that somehow seem to have changed after surviving the night of the disaster out in the open.

Somewhat similar to Invasion of the Body Snatchers, the show told the story of the aftermath of a hurricane in which water-based creatures infiltrate a small Florida town and begin to take over the bodies of the town's inhabitants through a cloning process (by first merging with then replacing them).
