It's summer and the heat is intense. Mary Rock, Kate Quinn, Tory Sweety and Stacy Crystal feel totally oppressed in the city and decide to take a few days off in the mountains to relax and enjoy the fresh air. They also join an outdoor sports association that offers a variety of activities such as biking, paddle boarding, rock climbing and white water rafting, all carefully supervised by qualified instructors. You will never see outdoor sports in the same way again.
