Climber Caro North and skipper Marta Guemes share a passion for venturing into the unknown. They soon hatch the idea of setting sail from France with an all-female team and heading for eastern Greenland to climb there. For Caro this is a long-awaited opportunity to open up new bigwall routes. After two years’ preparation, the team of climbers and sailors plus a filmmaker finally sets sail. Sedna, the goddess of the seas, puts obstacles in their way, but the Brave Seven master the challenge with tenacity and plenty of humour.
