Three teenage girls, Ellise, Fran and Agnes, join a potholers'' club in Derbyshire and go with other club members on a trip to the Peak District National Park. Their first visit into a cave leaves them excited and hungry for more, so they decide to go to the cave again. This time, however, the girls are alone, so a difficult and at times dangerous adventure begins. Ellise, Fran and Agnes not only show that ?where there is a will, there is a way'', but they also achieve greater selfawareness and self-esteem.
