Mistress Arianna, clad in black leather and brandishing her riding whip, puts her health club bosses through a nightmare of punishment and pain. This is her revenge on Joe and Slave Jack, who have been on her case at the gym. Penetrating the vulnerabilities of her male pony slaves by using a ball gag, nipple clamps, and an array of paddles, this magnificent, super dominant woman forces the supposedly macho men into slavery and bondage, shattering her bosses into meek, docile slaves.
