An SUV spill imperils Larkin, who's lost in the Glades. Seriously injured and fearing for her unborn child, she must depend on the kindness of a mysterious stranger, who gives her a lift. Meanwhile, a desperate search is launched by a fretful Russell, who's accompanied by Dave.

People who went missing during the hurricane form a support group that meets at the church, and Dave looks for evidence that they are somehow different than they were before. Meanwhile, Russell investigates toxic zones in the Everglades, where everything died after the storm.
