Plot synopsis: "Cleavage" is an uplifting and informative journey to the most eye-catching destination on earth: The space between a woman's breasts. Cleavage is what happens when breasts collide--a merger that at once fascinates, scandalizes, and mesmerizes. Cleavage makes movie & pop stars, enriches surgeons, tempts politicians, and dominates fashion. When breasts are lifted and pushed together, all of society rubbernecks.
