Cum Canyon takes place outdoors in the scenic canyons and beautiful desert surrounding Palm Springs, California. The bareback adventure follows super-star Matt Sizemore on his exciting hike in search of daring and reckless hikers wandering the dangerous edge of Cum Canyon. No happy trail is left uncharted, not a crevice or cave goes unexplored, and nothing unnatural stands in Sizemore's way as he scales the bottoms of the mountain to stand as the top — spewing his loads in thirsty holes along the way.
