Bertha's lair is a playground of pain, where bodies are canvases for her sadistic art. She binds her latest acquisition, a lithe, trembling form, to a St. Andrew's cross. The room is a gallery of implements, each one promising a unique dance of ecstasy and agony. Bertha selects a single-tail whip, its crack echoing like a gunshot, and begins her masterclass in masochistic bliss. Every lash draws a cry, every cry draws a smile, and the dance continues until both are spent.
