The team investigates the legendary Otterman, know by Alaskan natives as the "Kushtaka," who is believed to have the ability to shape-shift. Todd builds a Ring of Fire trap, and the rest of the team utilizes Crusty's airboat.

Hot on the trail of Alaska's Tiger, Todd devises a Blow Gun Trap, while Levi figures out a way to wirelessly trigger it. The team must take to the marsh after a creature that legend says gets a black stripe down its back after every human kill.
