Casting brother and sister twin cubs, this tale focuses on their education and reveals their individual characters: while the young male replicates perfectly the seal hunting techniques, his sister plays or rests. After the weaning period, the animals need to fend for themselves and adapt their cultural background to the ever-warmer summers. While the female tries in vain to hunt walruses, her brother successfully hunts for seals resting on drifting icebergs. Reducing her diet to easy-to-catch eider eggs and kelp, the she-bear can't sustain the energy requirements of her immense body. Growing thinner as rapidly as the glaciers, she fasts and finally meets a fatal end. Fortunately, her skilled brother reaches sexual maturity and migrates North to adapt to the changing conditions
