When a spur-of-the-moment romantic weekend in Venice has an unexpected outcome, Natalie Curzon thinks she's ready to take on single motherhood. But while it's love at first sight between Natalie and baby Freddie, being on leave from the office, alone all day with her baby and her post-pregnancy hormones, makes her feel trapped in some alien body. Just when she's at her wit's end, a major electrical issue in her London home leads Natalie to a whole new circle of friends. There's handsome, dependable Gary the electrician, and his assistant's young girlfriend Tiffany -- also the mother of a surprise baby. A crazy impulse leads Natalie to invent a husband who's working in Dubai, but when she and Tiffany decide to start a baby group, Natalie finds her lie spiraling out of control. Then Freddie's real father, Jack, unexpectedly reappears, and Natalie realizes just how much there is to win or lose...not just for herself, but her baby as well.
