In Idaho, the crew arrives only days before the wolf's status as a protected species is lifted, with local farmers indicating their intention to begin hunting them.

In British Columbia, the impact of global warming on the salmon population is felt by the bear whilst in Namibia, the uneasy co-existence between leopards and local farmers is highlighted.

In the first episode, Ray Mears arrives at the 270 square-mile Erindi Game Reserve in Namibia, a territory he describes as "one of nature's richest environments".

He is joined by his wildlife cameramen: Isaac Babcock, Shane Moore, and Natasha De Woronin, who runs the Global Leopard Project.

In the third and final episode, Mears and his wildlife crew turn their attention to tracking wolves in the Sawtooth Mountains of Idaho.

The following day the team gets a sighting of a small group of wolves and eventually comes across an entire pack of around a dozen, following the lead of a silver-backed alpha male.
