A bare back fills the screen—blemishes and imperfections displayed—when a startling slap is heard and the frame changes. The back appears again, and this time a pink welt is visible. Another slap, another frame change, another deepening welt. This continues for nearly four minutes, as a hidden assailant— the viewer never sees a hand—strikes over and over, continuously slapping up and down the exposed area. The blows draw more and more blood near the surface of the skin, and by the end the video the entire back is blotchy and discolored.
