The fourth grisly instalment in the Scream Street series. Party-loving zombies Doug, Turf and Berry are psyched, man! The underworld's greatest rock festival, Deadstock, is taking place in Scream Street and the community is soon swamped with rotting revellers from across the globe. It appears that Luke, Resus and Cleo will have a soundtrack to their search for the fourth relic - a slice of flesh from a long-vanished zombie. But Sir Otto Sneer has other plans. After an unsuccessful attempt to pull the plug on the concert, he banishes the headlining band, Brain Drain, to the evil Underlands. Now the race is on for Luke and his friends to bring them back - before it's too late...
