Your band, the Call of Cthulhu, is to play the Vaster Hills Rock Fest, but your roadie runs your van off the road--as a huge explosion replaces the festival site with a mushroom cloud! Now you're stuck in a nuclear wasteland! And something out there is still alive--and stalking you! Could it be a dread Hound of the Hindermost? A madcap Rock 'N' Role-playing event by CoC contributor William A. Barton, designer of the Rock 'N' Roll Star RPG.
