But when lightning ignites a raging forest fire, Kat''s cabin is cut off from the rest of the camp, separating Lily and Nirav from their parents. Left with no choice, Kat, the children, and the dogs must flee on foot away from the ravenous flames. As a frantic rescue mission is launched, Kat drives the party deeper into the mountains to escape the inferno.
