In an underground lake in Antarctica, researchers hope to study previously unknown microbial organisms. However, what they discover is far more astonishing: perfectly preserved dinosaur corpses. After one of the bodies thaws and awakens with a ravenous hunger, it becomes clear that death is not necessarily the end and that life always finds a way. Environmental activist Alex Ramirez, son of the expedition's paleontologist, came to Antarctica to save the organisms from extinction. Now he must quickly learn that it is the human race that needs protection.
