Meredith Moore is the perfect continuity girl. An on-set film script supervisor, it is her job to make sure every frame of the pictures is consistent with the one before. She is the error catcher. The needle-in-the-haystack finder. A cigarette in the left hand when it should be in the right, a prematurely melted ice cube in a half-empty glass of Scotch, a stray lock of an actor's hair -- these are the details by which she measures out her life.

But when Meredith wakes up on the morning of her 35th birthday yearning for a baby, her personal sense of continuity is thrown into flux. Determined not to marry, she impulsively flles to London to reunite with her eccentric mother and accept a new job on a well-known producer's film set. Her covert plan: to become a sperm bandit and find an unsuspecting donor to father her child.

Navigating London's murky social waters, Meredith is thrown into a strange new story, one that quickly spins out of control. In her quest to get pregnant on her own terms, she will accidentally uncover a web of secrets that will change the way she envisions both her working life and the nature of love.
