After spending many years in artificial hypersleep, a handful of survivors of the exploration vessel Supernova awaken to find their ship torn to shreds. They are unsure of what happened in space or how they crashed into an uncharted planet. Upon exploration of the new world, they soon realize their destination: The Triassic, the first chapter of the Mesozoic Era. A plan is formulated to escape this terrifying landscape plagued with dinosaurs and prehistoric beasts. The survivors soon discover that there may be an even larger threat looming under the trees than just the dinosaurs, threatening to cut their mission short and trap them all forever in the primitive depths of the Triassic.
