Morgan is a single, successful Boston realtor just assigned an old manor house deep in the woods, hours away from the city. There she unexpectedly runs into a potential buyer -- a mysteriously masterful man who unearths her sexually submissive nature down in the cold, dark cellar before he even tells her his name. The dangerously kinky encounter shocks her, yet when they meet again she can't resist doing whatever Simon says as he introduces her to the demandingly seductive world of bondage and domination and initiates her into the sacred dimension of erotic pain expertly balanced with intense pleasure. But increasingly drawn to Morgan and concerned for her safety, Detective O'Brian, a police officer trying to find a missing woman, begins challenging Simon's powerful hold on her by arousing more tender and yet equally irresistible feelings inside her.
