Upon returning from a mission in time, the TIME BRIGADE is captured by the Fairy Queen VIVIEN and find themselves prisoners on an Earth where Camelot never fell and continued to exist. They learn that Vivien seized the Holy Grail, and its mysterious powers enabled her to protect Camelot. She sees the Brigade as a threat to the existence of her world, and seeks to kill them. Our heroes are delivered by PARSIFAL, king of the Nuclear Knights, descendants of Arthur and the Round Table. But they soon discover that this Camelot is a rigid techno-medieval nightmare, from which all progress is banned. Parsifal realizes that the Brigade is a threat to him too, and also wants to destroy them... A spectacular comics fantasy by Jean-Marc & Randy Lofficier and Timothy J. Green II.
