The BAU are called to Oregon in order to investigate body of a young woman that was found displayed in Shakespearian garb inside a burned out insane asylum. When another woman falls victim to the same type of ritualistic murder, the team begins to suspect that the UnSub might be a Satanist. In truth, they are chasing a delusional man who is attempting to fulfill the wish of his equally delusional mother – to rid the world of 'Satan's brides.'
