Filmed over two years in a remote part of the Canada. Cameras observe a young female grizzly as she grows into adulthood. Filmed over two years, the documentary features vistas of open plains on the Arctic Circle and frigid rivers in vast mountain ranges. Against the backdrop of the vast Yukon tundra, the climate changes from frigid winter to spring thaw with a brief sunny season in-between. The cast of characters features hulking male grizzlies, mothers and cubs socialising until the salmon runs begin. Female bears must consume enough salmon during this brief time in order to sustain the cubs that will be born during the winter.

Going down into these narrow flooded passageways is not for the faint-hearted but, with only an estimated one percent of the caves explored, it is an opportunity for the team to write themselves into cave diving history, by pushing further in than anyone has before. This is a challenge that tests even the most accomplished cave divers. Steve must face the terrors of being lost in an underwater silt cloud in a cave. But there is a bigger issue at stake. All life in the Yucatan depends on the fresh water in this network of caves, but it's being contaminated by human development. With every metre the team maps, it adds to the knowledge of the system, which, in turns, helps protect it for future generations.
