This Abbott and Costello horror-comedy flick features the bumbling buddies as railroad baggage clerks who receive a strange shipment -- the last remains of Dracula and Frankenstein's monster. Trouble is they're still alive! When the deadly duo escape to a remote island, Abbott and Costello follow their trail and find not only the two ghouls, but also a mad scientist who wants to switch Costello's brain with that of Frankenstein's monster.
