AFTER AN ACCIDENT, Johanna’s leg was so injured that she almost lost it to necrosis. Part of her treatment was free diving under the Arctic ice. She describes the pain of the first few times in the freezing water as “agony”, but she got used to the sensation and now she holds a world record for the sport that saved her leg. British director Ian Derry joined her on a dive under the ice in this incredible short video.
