Casey Anderson scours Canada's wild West Coast for clues to reveal who or what is terrorizing Vancouver Island: are these wolves, monsters, or a little of both?

In the barren desert southwest, Casey Anderson struggles with thorny cactus, rugged terrain and intense emotions to stop a predator he loves, the mountain lion, from devastating fragile populations of bighorn sheep.

Casey Anderson pushes to the frontlines of a vampire bat invasion in Texas and drops into the darkness of the "torture chamber" deep in the juggles of Mexico to discover what will be at stake when vampires arrive in America?

Casey builds a custom “Super Moose” and goes undercover to explain bizarre and unpredictable moose behavior during the peak of the mating season – when moose leave behind their solitary day-to-day existence to gather in a spectacular hormone-fueled frenzy known as a “supergroup.”

A changing Everglades is putting pressure on its two most iconic predators: the American alligator and American crocodile. As crocodiles move north, their ranges are increasingly overlapping with gator territory. In this episode, Casey travels to the Florida Everglades to see which of these animals will reign supreme.

Casey is haunted by an old campfire tale that goes something like this: just as darkness falls, a Grizzly turns up in camp; but this is no ordinary Grizzly - it's a bold, aggressive predator, concealing itself in a cloak of darkness – a "Night Grizzly." Now, Casey will embark on the first-ever mission to understand, once and for all, if this legend has real teeth.
