When the boys are bailed out, not by Wilbur's doctor girlfriend but by a beautiful female insurance investigator, they find themselves caught up in a web of deceit that leads directly to a mysterious island laboratory complete with hidden passageways and suspicious experiments. It seems that Count Dracula, in the guise of a foreign neurosurgeon, has plans to replace the rebellious brain of the Monster with Wilbur's less astute, more malleable brain, so that, after a full recharge by a bolt of lightening, the monster will do Dracula's bidding. But they didn't bargain on Lawrence Talbot, who has been on their trail all through Europe, and who, by the light of the full moon, turns into the vicious and uncontrollable Wolfman. In the climax, Chick and Wilbur desperately try to escape and evade the battling monsters as the laboratory crumbles around them.
This classic comedy romp has most of the original actors reprising their Universal Studios monster roles, while Bud Abbott and Lou Costello deliver the laughs in their classic comedy style. It's a family-friendly good time that's more comedy than monster movie and a great introduction to the world of classic black-and-white movies.
