The wardens of Region 1 and 3 set off to educate the public on Montana's aquatic invasive species population. Meanwhile, a tribute is made for one of Montana's honorary wardens.

It's all hands-on-deck for the wardens when they handle decapitated deer and a poached trophy bull elk. Meanwhile, as a winter storm brews, wardens join forces in hot pursuit to catch a decoy shooter and a hunter caught in a web of lies.

Wardens stumble upon a heated situation on the side of the road; Lesofski searches for the culprit behind an elk carcass; a riverside check station cites four minors under the influence; underage drivers are caught behind the wheel.
