Swamp People - Season 4 Episode 12 Devoured

A massive sinkhole consumes part of Troy Landry's hunting grounds and he and his sons must race to his remaining lines in the same area before they are swallowed up. "The Beast of the East" is chased by swampers using gator calls and while one team comes up with a clever way to extract gators from a huge snarled lily field, another bravely hunts for "The Monster of Monster Marsh" while trying to outrun a deadly lightning storm. The biggest gator of the season so far is caught and wrestled onboard.
