As Christmas approaches, Billy and Maire Taylor are going through an emotionally-draining divorce after nine years of marriage. They have always been aware of their differences--he's artistic, she's business-minded--which he always thought made their relationship more exciting, but now she feels it taking its toll. She does realize that those differences are what has made their business work (a retail store called Poet's Walk selling Billy's designed greeting cards), but she now wants to sell the business in the break-up of their marriage, Sean Miller representing the company interested in buying. Things change when a little girl calling herself Taylor invades their house, looking remarkably like the girl that Billy has just sketched. After some missteps in trying to find out who she is, Billy and Maire learn that she is an angel whom no one else can see, an escapee from heaven who wants to be their daughter. They might not be able to overcome all their marital differences, but both Billy and Maire focus on Taylor, unaware that her mission is to make them fall in love with each other again so that they won't get divorced; she has a special interest because of something in the couple's past. Sean's presence in their lives complicates her task, especially when he admits that he wants to be more to Maire. Can she reunite Billy and Maire before her heavenly handler Donatello catches up with her?—Huggo
