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, and this season, he's threatening the bayou's swimming holes, and must be stopped at all costs. Also: master hunter Junior Edwards and his older son, Willie, make their special hunting weapons, specially designed hooks. Another father and son team, Trapper Joe LaFont and his stepson Tommy, also hit the marshlands, where careless Tommy puts his life at risk.
