When a group of Nationalists use an ancient artifact to bring a villain from Arthurian myth back from the dead to gain power, ex-monster hunter Bridgette McGuire escapes her retirement home and pulls her unsuspecting grandson Duncan, a museum curator, into a world of magic and mysticism to defeat a legendary threat.
A standoff between Duncan, Galahad, and Lancelot is all that’s preventing the Otherworld and our world from colliding...but only one of them can be the greatest knight and Duncan better hope it’s him. And, of course, there’s a DRAGON.
