The synopsis goes something like this ...
Considered one of the comedic duo's best movies, Abbott amd Costello play a pair of freight handlers, Wilbur Grey and Chick Young, whose world is turned upside down when the remains of Frankenstein's Monster and Dracula arrive from Europe to be used in a house of horrors. Dracula awakens and escapes with the weakened monster, who he plans to re-energize with Wilbur's brain, while Larry Talbot (The Wolf Man) arrives from London and teams with Chick in an attempt to thwart Dracula. However, when the full moon rises all hell breaks loose with the Wolf Man, Dracula, and Frankenstein's Monster running rampant.
