在这部野生动物系列 北极熊：北极勇士片中,地球上很少有地方象北极一样荒凉——数月的极夜，暴风雪，冰冻和极光，这里生活着世界上最强壮，最令人敬畏的猎手——北极熊。
They're as beautiful as the snowy landscape they inhabit, but life is tough in the Arctic, and these bears have to be strong to survive. Winter means months of darkness, blizzards and ice, while summer brings continuous blinding sunshine. The polar bears roam thousands of miles searching for food, while pregnant females fast for months raising their cubs in remote snowy hills. This film follows the bears over a year and captures remarkable scenes of birth, cubs playing and underwater footage that reveals the unexpected grace of the bears swimming.
