With just three days left in the season, a team sets off to find a serial killer gator named "The Reaper" that has been snatching cattle from ranches in the middle of the night--while another veteran team is plagued by catching alligators so big, they can barely remove them form the swamp. A legendary swamper rallies his family to leave their boats behind and hunt beyond deep in the woods of the bayou.

On last day of alligator season, a massive cold front hits the bayou--driving swampers to extreme measures in order to tag out. One hunter is forced to make the risky move of crashing his boat through a beaver dam, while another hunter puts his life on the line to save his beloved partner.
