Ayla loves climbing. But she prefers to climb indoors, with all her safety harnesses in place and soft mats to land on. Her climbing partner and best friend, Lissy, is much more adventurous and loves the outdoors. When Lissy starts hanging out with Carlos, the new thrill-seeking guy in town, Ayla wants to keep an eye on her and finds herself tagging along on a weekend climbing trip up Black Dog Mountain. But things go very wrong when Lissy and her dad, the only adult in the group, are badly injured high on the side of the mountain. Suddenly the risks of climbing become very real. Ayla and Carlos need to figure out how to get help, and every decision they make could have catastrophic consequences.
