It's quirky denizens know not to venture too far into the swamp, not unless you want to run afoul of spirits, monsters and alligators.

When deaths due to animal attacks seem to suggest a wolf-like creature, Jax and Hailey must get to the bottom of the crime spree gripping the bayou town, before whatever they are hunting starts hunting them.
