Lily is a 40-something marriage counselor in a wealthy area of London. She helps struggling couples who come to her for advice. You’d think she’d follow her own advice, but that’s not the case. Ania is married to a businessman who works in the city, is constantly on the move or cheating on her with Kim, a young student. Feeling abandoned, she starts a very private book club with some of her patients who have become friends. To break out of their daily routine, they experience the erotic adventures of the women in their literature. Whether with one or more strangers or just among themselves, Lily, Claire and Melissa fulfill some of their deepest desires and fantasies while remaining faithful to their husbands.
