When a group of creatures, who claim to be benevolent aliens from earth's distant past, reappear, Dr. Peter Kenner struggles to reconcile their existence with his once held religious views. He turn to his uncle, a retired scientist and man of strong Christian faith, for help and insight. Meanwhile, Sarah Pennington seeks protection for her young daughter, Kara, believing extraterrestrials are bent on abducting Kara as they did her husband three years earlier. Kara, a spiritual and highly intelligent nine-year-old, has a very special gift - one that threatens to expose the nature of the extraterrestrials. Josh Sanders, Pete's uncle, is the focal point that brings Peter, Sarah and Kara together - all under the influence and advice of the mysterious stranger, Ethan. Are these beings really ancient aliens sent to protect humanity as they claim to be? Or are they, as Josh believes, fallen angels set on deception as the world approaches the last days?
