Molly Roden Winter is a caring, but worn-out mother of two sons, and a devoted yet lonely wife to Stuart. A life filled with worries about the children, household chores, and exhaustion by evening turned into something like a worn-out record. But everything changed after one family misunderstanding, which led to the decision to open their marriage.
One day, when her husband once again refused to help with putting the kids to bed, Molly went outside to clear her head. She ended up in a bar, where she met a young man who showed interest in her. It made her feel wanted again and awakened passion in her. That same night, Stuart suggested they try dating other people—an idea that also excited him.
Now the spouses not only define the boundaries of their new relationships, but also face jealousy, constantly asking themselves: will they be able to feel for others while staying attached to each other within their marriage? Will their experiment lead to strengthening and happiness in the family, or will it end in the collapse of their union?
