Teen survival instinct. An exploration of the natural maturation and sudden flaring up of teenage survival instinct whenever they are faced with mortal danger in life. The Hansen children plead to go on a camping trip for their vacation. Since Jill, their mother, has no time at hand, she suggests that her most-trusted brother, Roy, goes with them, obscure to the fact that it was the beginning of a different life for her. The children, after the death of Roy find themselves in a forest, face-to-face with, on one hand, ravenous beasts of prey and an unnatural human habitat. A fierce battle for survival rages on at various levels until blood is shed. Each of them fights for dear life, but who, among the three, will survive?
