An Imp named Samwise approaches Aahz and Skeeve to get them involved in his pyramid scheme. Skeeve is skeptical, but to his surprise, Aahz is interested in owning a piece of the rock. They discover that everything is not as Samwise described it – he completely forgot to mention the curse, or the wizard he got angry at him.
In the meanwhile, Skeeve is trying to improve his luck with women, but the bad luck haunting the pyramid affects him, too. Both of them need to figure out how to deal with the Mumsy’s curse, or spend the rest of their lives in a deep, dank dungeon.
