Follow French kayak superstar Nouria Newman and two childhood friends, as they navigate one of the world’s most challenging sections of whitewater: the Rondu Gorge of the Indus River, in Pakistan. Documenting Nouria's attempt at completing the first integral descent of the Rondu Gorge by a woman, Big Water Theory is a compelling exploration of human spirit and the relentless pursuit of adventure. It offers a powerful and inspiring, yet highly detailed and informative look at the world of extreme kayaking. Set against the stunning backdrop of the Karakoram mountains, the film highlights the irreversible nature of the sport, with heart-pounding descents that test the kayakers' psychological and physical limits.
