A look at the challenges young animals face, from their first steps through to leaving home. For any animal, the early days of life are often the most difficult. Finding food, avoiding predators and generally learning life's essential skills is tough. However, with a little parental guidance growing up can be an adventure. By following some special tiger cubs in India, an adolescent mountain gorilla in Uganda and two nervous polar bear cubs in the high Arctic, the trials and tribulations of growing up wild are revealed.

In the wilds of the Canadian Rocky Mountains, a mother moose tends to her newborn calf. Spring is in full swing, but this far north winter is never far away and, with hungry bears and wolves for neighbours, many challenges lie ahead.

Local cameraman Hugo Kitching knows this only too well, but he is determined to follow the mother and calf through the four seasons. What unfolds is a very intimate story, and when Hugo finds a second moose calf born late in the year, things take an unexpected and dramatic turn.
