On an ordinary night, UFO came to earth. It shone wonderfully on two children and a miner, and left a mysterious pattern on a stone in the mine. Years later, when the two children grew up, Wayne became a local policeman and Jennifer became an astronomical scientist. When Jennifer came to the town for a field trip, he met the miner who was throwing dismembered cattle and human limbs into a mysterious tunnel. The miners tried to kill them, but a gust of air dragged him into a bottomless abyss. It turned out that the UFO chose Jennifer, Wayne and the miner as representatives of mankind to accept extraterrestrial justice and truth, and the pattern left on the rock was the date of departure. But the miners devised a plan to plant dirt and frame it in order to take advantage of the opportunity alone. UFO arrives as scheduled, and Jennifer and Wayne enter the cabin to accept justice and truth. Soon, when they are sent back to earth, can they bring peace and happiness to mankind?
