As the sun rises on day 18, it's already 96 degrees on the bayou. Every hunter knows the heat drives the gators into a feeding frenzy. But the scorching sun can spoil hides and meat once the gators are in the boat. Troy and Clint are targeting Lake Verret to make the most of the voracious gators. Junior Edwards is also expecting a huge day. Five years ago, in 105-degree heat, he had the best day of his career. Today, he's hoping to repeat past glory. Liz and Kristi are primed to fill the boat by midday, and Liz is on the verge of her best catch all season. But soon, things turn on a dime when the swamp throws Liz a curve she never saw coming. Across the swamp, veteran hunter Bruce, Ron and Tyler are looking to cash in on the heat wave by targeting a hunting ground called "Cypress Graveyard." It's part of local lore, and Bruce believes it will deliver, but getting there is difficult--it lies at the end of a maze of canals that can confuse even the most experienced swamper.
