And this, is why you don't dabble in the dark arts if you don't know what you're doing! Invocation stars a sexy and busty goth babe who has been reading a book of spells by candlelight. She recites the verse aloud, completely unaware of what the spell does. As a storm brews outside, a portal to another dimension opens in her house. She's terrified at the hellish demon that she's inadvertently summoned, knowing he could easily destroy her without lifting a finger. She's disgusted, but at the same time relieved when she realizes that it's not her life or her soul that the demon wants - no, it's that hot body of hers!
