Samuel Campbell is a park ranger from New York City who enforces natural areas and defends animals from illegal hunting or poaching activities. He visits and enforces Acadia Park in Maine when he hears animal cries. Investigating he finds an infant moose and a yellow dog in a metal trap. The dog is Fuzz, and he informs Samuel that his former master, a greedy hunter, had abandoned him, and had left him and the moose in the trap, in order to lure a wild fox that he wants to shoot and kill. Wanting this anarchy towards animals to end on the coastal park, Samuel encounters the hunter to fight him and end his scheme.
