Rowena "Ro" is a high-spirited 12 year-old who is experiencing a lackluster Christmas. Ro isn't handling her parents' divorce well. She wants her life back the way it was—her parents back together, her dad's new girlfriend and son out of the picture, and their family traditions to remain the same. After a disappointing celebration with her family, including her sister Gabriela "Gabby," Abuela Sofia and Abuelo Hector, she makes a wish to a neighborhood Santa for a "do-over" and unexpectedly finds herself reliving Christmas day over and over … and over again. Now, in order to break the strange magical loop, Ro must learn to appreciate her loving family as it is, as well as the true meaning of Christmas.
