The Starlost | 1973
The series is set in the year 2785. Unable to marry the wealthy Rachel because his parents are poor, Devon speaks in protest during ritual services. Deemed outcast and anathama by the elders, he is sentenced to death for his actions. Escaping his bounds and seeking a place to hide, Devon enters a forbidden cave wherein lies the Earth Ship Ark. As he explores the ship, he touches a control panel that activates a computer, and from its host, Mulander 165, Devon learns that in the year 2290, a great catastrophe threatened all life with extinction. As he listens, the computer host tells him that the Committee of Scientists built Earth Ship Ark to transport specially selected Earthlings to other planets.
The Earthlings are suspended in an organic cluster of environmental domes called biospheres and isolated to preserve their special human characteristics. Devon then learns that Ark was launched to seek and find the solar system of a "class six" star similar to the sun, but "there was an accident... Ark locked in collision course with Class G Solar Body, an unidentified star. No further data recorded." Returning to his home in Cypress Corners, Devon seeks out Rachel and they return to the ship. They are followed by Garth, the man who is pledged to marry Rachel. Unable to persuade Rachel to return with him, Garth remains, determined to protect Rachel from Devon.
The series depicts their adventures as they explore the various biospheres searching for someone or something to explain the mystery of the great catastrophe and save the remains of Earth life by finding the star they need and helping his people, "the Starlost," to find a home.
