After hearing about a bat creature spotted in Beanotown, Dennis and Gnasher go on the search, and come to the conclusion that there is a vampire on the loose. Dennis calls on Curly and Pie Face to help. At first they are not sure who the vampire is, but looking at the signs, they realise that the vampire is the Colonel. Dennis and his friends try to prove it, but their quest leads them to find the Colonel with all the other residents of Beanotown - meaning that they are all vampires.

Refusing to be beaten by vampires, Dennis and his friends launch an attack, only to be faced with the truth - that the residents are all gathered for the Beanotown Founders' Day and the 'proof' against the Colonel was all very simple. Dennis's imagination gets him into trouble again.
