The USS Enterprise is exploring the center of the galaxy, looking for the heart of creation. When the ship is caught inside a tornado made of pure energy, a devil like being calling himself Lucien appears to save them. Lucien takes Capt. Kirk and his crew to the magical planet of Megas-Tu. But when the Megans discover the presence of humans, they put them on trial the same way they were treated when they visited Earth centuries earlier.
