Somewhere in the dark and nasty regions where nobody goes, stands an ancient castle. Deep within this dank and uninviting place lives Berk, overworked servant of The Thing Upstairs. But that’s nothing compared to the horrors that lurk beneath The Trap Door.

The Trap Door follows the adventures of Berk, Boni (a moaning skull), and Drutt (a small strange-looking spider). Berk is constantly interrupted as things emerge from The Trap Door to make their lives a little more difficult. But then it’s his own fault, as he constantly leaves it open. But then if he didn't leave it open, there wouldn't be a show. Catch 22, really.
