Troy, Chase, and Bill gamble on a long journey into the center of the Everglades, following the migration of giant pythons to the furthest depths of the wetlands. Meanwhile, Bruce and Zak head deep into outlaw country, looking for snakes hiding on a deserted bootlegging trail...but what they uncover is far more shocking than they expected.

 As a heat wave grips the Everglades, Bruce and Zak call in canine reinforcements to sniff out serpents hiding from the rising temperature. Meanwhile, Troy, Chase, and Bill hunt the remote jungles of snake island. But when a differing opinion on strategy divides them, Troy soon finds himself alone in the middle of nowhere.
