As the Arctic polar ice cap melts, reaching the North Pole has become increasingly dangerous. But an expedition of women from East and West, led by explorer Felicity Aston, set an audacious goal of skiing to the North Pole. Filmmaker Holly Morris and an all-female crew document this daring and unprecedented group as they navigate everything from frostbite and polar bear threats to sexism and self-doubt in an intimate story of resilience, survival and global citizenry—in what may be the last ever over-ice expedition to the top of the world.
