Welcome to one of America's last frontiers: the wild swamplands of Southern Louisiana, a place whose history stretches back to the 17th century. It's the start of the most exciting--and dangerous--time of year for the swampers, the month-long alligator season. During this 30 day window, swampers make most of their annual income culling gators. Troy Landry, a Cajun whose family goes back three generations is on a mission to hunt down his own personal "white whale," the notorious Big Head, a monster gator he's been after for years. This season, Big Head is threatening the bayou's swimming holes, and must be stopped at all costs. In this episode, we also meet master hunter Junior Edwards and his older son, Willie, as they make their special weapons, specially designed hooks. Another father and son team Trapper Joe L'enfant and his stepson Tommy, also hit the marshlands, where careless Tommy puts his life at risk.
