Polar Bears are well adapted for life in a frozen snow-covered environment. However, during summer and early fall, Hudson Bay is ice free. This film follows the bears throughout summer, unraveling the difficulties in their fight for survival at a time of plenty for all other Arctic inhabitants. By early July, the bears are cast ashore and live off resources acquired during the winter. Cubs born in December experience for the first time the explosion of life during the colourful Arctic summer.
