Based on the game series of the same name (but relating a story not told in any of the game's versions) which was itself based on a series of books, THE WITCHER revolves around a magical world in which witchers -- genetically enhanced humans -- have special monster-slaying powers. They were once a common sight, but now Geralt of Rivia (Henry Cavill) is one of the last of his kind, despised by the villagers of the towns he travels through on monster-killing missions. His only wish is to endure and survive as simply as possible, but when an unreliable magician Stregobor (Lars Mikkelsen) lures him to his lair to enlist his help in a scheme to wipe out a possibly cursed generation of girls born after an unusual eclipse, he runs afoul of forces both magical and political just as an Elf revolution is brewing. Meanwhile, Ciri (Freya Allan), a deposed princess with mysterious powers, is on the run after her kingdom was invaded by soldiers who seem bent on capturing her, and downtrodden teen Yennefer (Anya Chalotra) painfully learns the ways of magic from mysterious sorceress Tissia (MyAnna Buring).
