Sir Differel and Lady Margaret--aka Dribble and Maggot--are best frenemies, though why even they don't know. Despite a facade of antagonism that can make it appear that they are ready to scratch each others' eyes out at any moment, they respect and trust each other, they confide secrets they won't tell anyone else, and they each help the other when necessary, whether it be working on a school project or fighting monsters.
Dribble and Maggot share frequent visits, usually consisting of sleepovers at Differel's ancestral manor. During one of those, Maggot encourages Dribble to lose her virginity, and when she expresses reluctance, they sneak into the buttery off the butler's pantry to steal a bottle of liquor. However, to avoid being caught they must hide out in the catacombs under the house. There, Maggot reveals the real reason for her visit: she fears she may be pregnant.
However, they soon discover they have worse problems, when they are attacked by a horde of goblin-like creatures and become trapped, unable to flee. And no one knows where they're at!
Can they survive long enough to be rescued, or will the goblins drag them back to their secret lair to subject them to unspeakable acts?
