Invasive Burmese pythons are taking over the Florida Everglades and devouring everything in sight. The only way to stop them is to call in the nation's best swampers: King of the Swamp Troy Landry.

One week into the hunt for invasive Burmese pythons, the swampers venture into the foreboding Everglades Triangle. Bruce, Zak and Bill hunt near a mysterious abandoned rocket silo, while Troy and Chase scour a cattle ranch.

In the third week of fighting monster serpents, hunters face a terrifying reality: the invasion is bigger than they anticipated. With their backs against the wall, Troy, Chase and Bill call upon trackers and thermal drones to get a leg up on the snakes.

As the hunters face their final week in the Everglades, Troy and Chase protect a remote community from an aggressive gang of alligators. Then, the swampers join forces to track down a deadly hybrid python.
