An ordinary Saturday morning turns extraordinary for seventeen-year-old Dave Duggan when a couple of girls from his school ask for help in finding their way into the mountains beyond their town. After entering a dark area of rainforest, birds, bugs and small animals inexplicably begin to die around them. Dave's life is threatened and no reasonable explanation fits. Forced to take responsibility for three lives, Dave finds himself losing his heart while in very real danger of losing his life.
