Deep below the town of Dewberry, the Zombies and Vampires are unhappy with their life underground, and summon Count Dracula, their master. He promises them fun among the humans, disguised as the audience at Rock Concerts, where their bizarre appearance will go un-noticed. To achieve this, he holds a Pop Idol style audition and creates his own Rock Group.
Meanwhile Inspector Holmes of the Dewberry CID and his pathologist, Dr. Watson, are battling against the master criminal Professor Moriarty and his gang - as well as trying to solve the mystery of an outbreak of anaemia among the town’s teenagers.
These strands are woven together in a hilarious plot, full of splendid eccentric characters, sparked by a dynamic Rock score, which takes in 60's rock, a touch of 70's disco, and even a Line Dance!
