The Secret Diary of Katherine Stark is an erotic tale about a woman who enlists the help of an older man to escape a lifetime of submissiveness, abuse, and unhappiness, by entering a controlled master-slave relationship. This wickedly suggestive film is not for the faint of heart. Successful and business savvy Katherine Stark silently suffers an abusive relationship with Johnny Precious, an up-and-coming rapper, until an older colleague, Nicholas Anderson, suffuses her imagination and the landscape of her body with a rare and empowering passion. Through obedience and discipline, Katherine and Nicholas engage in a secret world where everything naughty is possible, and no arousing deed goes unpunished.
