A group of tourists is out hiking in the forest, when one man slips down a slope and lands badly, breaking his leg. Meanwhile Jake Klangford, a young Ranger trainee, is having what looks like his last argument with his beautiful girlfriend Jo. She is moving out of their cabin. Just then the phone rings- Jake's Father, also a ranger, has a job for him-he is being sent in to rescue the hiking party. His first rescue. With Jake's father piloting the helicopter, Jake is lowered down into the dense forest, heading off deeper into the trees as he looks for the hiking party and their injured member. The sun is shining, and this looks like it is going to be a simple first assignment...
