Richard, Matt and Julia have been involved with the London BDSM scene for a long time. But they find themselves jaded as what used to be dark, edgy pleasures are now too easily accessible and lack mystique. But when they meet Jason, 'Master Stern' and 'T-bone' all that is about to change. All three men are polygamists, each the alpha-male among a group of women. Arrogant, self-assured and convinced of their own status, the men are about to show Richard, Matt and Julia the true pleasures of polygamy, or so they think.
