For those who live there, Earth is both paradise and prison, a place for people to live out their lives with no hope of leaving or knowledge of what exists beyond this world. Then on one otherwise uneventful day, two odd-looking men from another planet suddenly appear with an offer the citizens of Earth can't refuse: the power to travel into the unexplored frontiers of the universe. But first, the Earthlings must prove they can bring peace to their world and show love for their fellow man. At first, Earth's inhabitants are skeptical of their new friends but soon realize the magnitude of the gift these aliens have offered. They are given five years to end their wars and create an atmosphere of peace and social harmony needed to impress the union of worlds. While the world is filled with excitement, the Reverend Jimmy Jordan questions his faith in God, which leaves no room for the existence of life beyond Earth. He studies the Bible in earnest to strengthen his beliefs, and he discovers a startling secret concerning Earth's new friends, one that could have dire consequences for the planet and the people living on it.
