This is the story of a modern day pirate mad man and his crew of eight, searching for fortune on a cruise ship but a small group of passengers fight back.

John Hall is a drifter who wanders into a small town in Maine. He needs a job and decides to seek employment at the community's top business: a large textile mill. He is hired to work the "graveyard shift" -- from around midnight to dawn -- and, along with a few others, he is charged with cleaning out the basement. This task strikes the workers as simple enough, but then, as they proceed deeper underground, they encounter an unspeakable monstrosity intent on devouring them all.

Count Dracula adjourns to Earth, accompanied by Frankenstein's Monster, the Wolfman, the Mummy, and the Gillman. The uglies are in search of a powerful amulet that will grant them power to rule the world. Our heroes - the Monster Squad are the only ones daring to stand in their way.
