C.S. Lewis wrote a trilogy of science fiction books called The Space Trilogy. "Out of the Silent Planet," "Perelandra," and "That Hideous Strength" are the three books that make up the trilogy. In the framework of interplanetary travel and interactions with extraterrestrial species, the show examines topics of theology, morality, and the conflict between good and evil. Every novel follows Dr. Elwin Ransom, the main character, as he travels through space and interacts with people on distant planets.
