This book explores the intersection of extreme sexual practices and the horror genre. It delves into films that combine elements of bondage, discipline, dominance, submission, sadism, and masochism with graphic violence and terror, often resulting in extreme trauma and bloodshed. The author rates and reviews 173 such films, posing a challenge to the reader to count how many they have experienced.

This work appears to cater to a niche audience interested in the extreme fringes of both horror cinema and BDSM culture. The author's direct approach to rating and reviewing films that explicitly combine these elements suggests a focus on visceral impact and thematic exploration. The premise sets up a critical examination of how these often taboo subjects are depicted on screen, likely appealing to viewers who seek out transgressive and boundary-pushing content. The book's structure as a catalog of reviewed films implies a reference-style utility for enthusiasts of the genre.
