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 USA's best swampers.

One week into the hunt for invasive Burmese pythons, the swampers venture into the danger-filled Everglades Triangle.

The hunters face a terrifying reality: the invasion is bigger than they anticipated, and their backs are against the wall.

As the hunters face their final week in the Everglades, Troy and Chase protect a remote community from an aggressive gang of alligators. Season finale.

Troy Landry, his son Chase and snake expert Bill Booth track serpents into a breeding ground known as Deer Haven; veteran swamper Bruce Mitchell and invasive species hunter Zak Catchem take on the legendary Skunk Ape Alley.

As the hunting season heats up, Troy, Chase and Bill dive into deep water to catch pythons, but could be in over their heads.
