Moses is a young man plagued with visions of a world so very different from Earth. His would-be-girlfriend, Zipporah, and his high school principal, Jethro, fear that Moses may be losing his mind. A voice calls out to Moses, calling him to take up arms and fight the Idols. When Moses answers the call, he is pulled aboard an alien starship. The ship's computer tells him strange tales of his origins, of a people enslaved on a distant world who need to be set free of their captivity. Moreover he is given Mitzvot, The Law, a giant robot with God-like power, so that he may stand against the enemies of all that is good.
