As a major storm rages in the Gulf Coast, Troy, Terral, Jacob and Dusty race to run their lines before the storm sinks their gators. Meanwhile, severe lightning forces Ronnie and Ashley to take emergency shelter, while a broken water pump threatens to sink Frenchy and Gee in the middle of a thunderstorm.

Before Dusty returns to Florida, he's determined to help Jacob bag a behemoth that's been eating other gators. Frenchy and Gee hunt for the beast that's been stealing all of their bait, while Troy and Terral ruthlessly pursue the deadly giant that killed their neighbor's dog. Willie takes on a 900 pound monster that's been taking bites out of his catches.
