After hooking up with the immortal Merlin again, Arthur sets about getting his old gang back together by finding the reincarnated versions of his Knights of the Round table. Lancelot is a French billionaire, Galahad is a suicidal futuristic samurai from Japan, Gawain is a South African father who ditches his family to go save the world, etc. It's interesting that the race-bending of the cast is actually part of the plot and that readers at the time didn't seem to mind it (today it would inspire hours of angry rants about DC being PC). Some did object to one part: Sir Tristan reincarnates in a female body but still identifies as a man, and instead of being used for comedy as most '80s comics would have done, we see the way he struggles with his sexual identity. The treatment of trans issues isn't perfect, mainly because the writer didn't know he was treating trans issues, but it's still pretty groundbreaking for its era.

Another source of drama is the fact that Arthur's trusted friend Lancelot and wife Guinevere can't help “reincarnating” their horniness for each other, but the fact that there's a sordid love affair involved just confirms that this is meant to be a prestige cable drama.
