Two best friends caught in a mysterious web of erotic pleasure, guided by the masterful stranger Jon Rush. Sophie's ordinary modeling job turns into a love affair with her photographer. Soon her sexy romps before the camera become sensuous scenes with bondage, leather, ropes, naked poses and the coolly distant Rush whispering orders in her ear. Submissively falling under the man's spell, she slips into San Francisco's sexual underground.. Urged by her own unexplored sexual desires, a frantic Maureen seeks to rescue Sophie. But, in so doing, she must submit to Jon and his world, Black Doors, a private sex club buried in a subterranean China-town basement. In Black Doors the sex is torrid and extreme, rife with the pains and pleasures of S&M and tawdry exhibitionism. Darker still are the shocking mysteries of a realm beyond Black Doors where women become nameless chattel, where they revel in the sexual services they offer those who own them.
