The second season begins with the hunters preparing for the 30-day season. Junior Edwards and son Willie get a larger boat; new hunter Terral Evans, who relocates alligators that are threatening humans to remote areas, goes out at night with his team.
Troy and Jacob try a new spot that they hope will help them with the 300 tags they have remaining; R.J. and Jay Paul spot evidence of a monster gator; and Joe and Tommy get a big gator on the line, but Tommy makes a mistake.
Troy puts new hire Liz Cavalier to the test when he hopes to catch 25 gators; a poacher hampers R.J.'s progress; the Edwards men run two boats at once; and brothers Glenn and Mitchell Guist join in the gator hunt.
Troy's getting his tags thanks to his sharpshooter, but he has a setback when the shooter's injured; loner Bruce hires a greenhorn who makes a costly mistake; Joe and Tommy hunt a cannibal alligator; and the Guist brothers hunt rabbit when the food supply runs low.
A storm nears Louisiana and the hunters make preparations; Troy and Jacob's sharpshooter recovers from an injury; Joe and Tommy are at odds over their plans for the day; and R.J. and Jay Paul hunt close to the Gulf, where they battle high winds.
Night hunting during a full moon increases risks for the hunters; Joe and Tommy go for shrimp rather than gators; Terrell Evans and his wife and friends search for a fabled alligator; R.J. and Jay Paul hope to catch a poacher who has troubled them; and Willie Edwards goes snake hunting.
The hunters try new places, with Troy switching spots as often as every three to four days; things are tense between Joe and Tommy when Tommy misses a day of work; and Glenn and Mitchell hunt squirrels for dinner.
Joe and Tommy part ways, and Joe hires a new hunter to take Tommy's place, while Tommy works with an old friend; Junior and Willie work together on the same boat; and duck hunters descend on R.J. and Jay Paul's favorite spot.
Tommy tries to prove he is an elite hunter and captains his own boat, but engine trouble threatens to derail his plans. Meanwhile, Troy approaches a prime hunting spot only to find that the area is covered with water lilies; Joe works to break in a new helper; and brothers Glenn and Mitchell hunt squirrels to make squirrel and dumplings.
Troy has engine trouble, which threatens his chances of tagging out early; Junior and Willie go to new hunting grounds, but Junior forgets to pack the guns; Bruce and Nick catch a mutilated gator; R.J. and Jay Paul use two boats; and Joe and Tommy fish separately, then reunite to face the end of the season.
