As the last day of the month-long alligator season dawns, the moment of truth arrives. Today is about one thing: tagging out before the season ends at sundown. Troy is determined to hold on to his crown. He's got only 14 tags to go, but to cement his reputation Troy wants one more monster gator...one that will make a statement to the competition. R.J. and his son Jay are down to their final tags. For this father-son duo, tagging out will mean that they've filled a bayou-best 500 tags this season. Bruce, Ron and Tyler are facing a daunting final day. The elements have wreaked havoc on Bruce's territory all season, and after Lake Pontchartrain overflowed during a storm, brackish water has chased most gators from the area. With so few tags left, Liz and Kristi are determined to finish fast, but soon, the mood sours. A fish kill from dropping oxygen levels in the water poisons the honey hole, and with so many dead fish around, gators aren't biting.
