But then a vicious horde of creepers attacks, delaying their escape. Soon the gang learns that there's a new villain behind the attack: a griefer so twisted that he'd rather stay trapped in the Overworld than live a mundane life in the real world - and he has no qualms about keeping every other player trapped on the server with him.
