"Commit to the Line" chronicles the adventures of women as they undertake an intense all-women mountain biking camp at Whistler Mountain in British Columbia. The camp is called Spokeswomen Mountain Bike Camp and features some of the most prominent names in women's mountain biking acting as camp instructors. The camp participants cover a wide-range of ability and age. The participants arrive at Whistler Mountain from all over the globe to experience the most intense downhill/freeriding mountain bike park in the world. Learning from the accomplished Spokeswomen instructors allows the women to move beyond their current abilities and accomplish extraordinary goals in this incredible, world-renowned mountain bike park.
It focuses on the experience of the film's director, Rachelle Dermer, who took the camp one year after finishing treatment for uterine cancer. She returns to the camp to make her film and ultimately takes the camp again at her two-year anniversary.
