The Black Door is a place of forbidden pleasures and where every woman's fantasy can come to life. The women in the Naughty Book Club – Naomi, Kennedy, Mira and Tyler – will go to any length to satisfy their erotic desires. While they keep that part of their lives a secret, their significant others are harboring secrets of their own.

• Naomi, a suburban housewife, is stuck in a loveless marriage and can't figure out why her husband won't have sex with her.
• Mira, the seemingly conservative CEO, has a wild side that could ruin not only her professional reputation but also her relationship with Sam.
• Kennedy, a flight attendant, is tired of looking for love in the wrong places, but the mystery man seated in first class might be just what she needs.
• When Tyler comes home early from her latest design assignment, she discovers her girlfriend in bed with a man, and it is all she can do to keep it together. Here they each begin their experience at The Black Door. Once certain truths are revealed, will the shock of knowing destroy relationships, or will they all just ‘play nice', and forgive and forget?
