Adapted from Arthur C. Clarke’s classic novel first published in 1953, the epic six-hour miniseries “Childhood’s End” follows the peaceful invasion of Earth by the mysterious Overlords, which begins decades of apparent utopia at the cost of human identity and culture.

 Karellen (Charles Dance), the ambassador for the Overlords, makes first contact with Earthling Ricky Stormgren (Mike Vogel). Karellen’s comforting words and amazing technological gifts quickly win humanity’s favor. However, Karellen’s refusal to reveal his physical appearance and insistence on dealing only through Ricky raises questions whether his intentions are truly benevolent.
