Polar bears are one of the most iconic animals on Earth, and yet we know so little about them. Apart from fleeting glimpses, scientists and filmmakers have never been able to follow individuals to tell their story and record details of their family life. Now, taking what he has learnt while making the absorbing series The Bear Family and Me, wildlife cameraman Gordon Buchanan embarks on an ambitious and dangerous mission - to gain the trust of a family of polar bears and, using this unique opportunity, observe the life of these enigmatic animals as never before, over the course of a year.
