Kate Harper gave birth to twins in an early Nebraska blizzard. She knows she heard two babies cry, but her husband and the nurse say one of her babies died. At her insistence, her husband lets her hold the dead baby and she grieves as she never has before. Kate wants her baby back, but knows that's impossible. A year later, her husband is dead, and desiring closure, she heads back to Nebraska to visit her baby's grave but discovers a baby at the grocery story who looks like her daughter. Did someone steal her baby?

Nick Kendall's wife died when her horse threw her, leaving him to raise their daughter alone. He's already gone through two nannies, and is looking for a third when Kate Harper applies for the job after they meet in the grocery store. She's great with the little ones, his and hers, although it's several days before he gets a good look at her daughter. When he ends up holding both tiny girls who look exactly alike, he's sure he's entered the Twilight Zone.

As Kate and Nick begin to search for the nurse who is the only one with answers as to what happened the night Kate's and Nick's babies were born, an attraction develops. Can love win out over so much pain and uncertainty especially when Kate fears Nick only wants to keep the child that should've been hers?
