Every year before Christmas break, the students in Olivia Mead's class present My Impossible Christmas Wish papers, but this year, something unusual is happening... The wishes are coming true. Olivia takes note, because she has a truly impossible wish - for a dad of her own, a husband for her single mom. A complete family. Olivia is soon convinced the answers are linked to a mysterious woman who she believes is an angel. Olivia discovers the mysterious woman, Elsie Waybright (Della Reese) is no angel, and she has plenty of secrets to keep, but she does have the answer to how the Christmas wishes came true. Her unlikely friendship with Olivia shows them both that anyone can be an angel to others, but when the wishes get truly impossible, good angels take the requests to God and not into their own hands...
