When Lucida is unable to finish her gift for the Baby Jesus in time for the Christmas procession, a miracle enables her to offer the beautiful flower we now call the poinsettia.
At Christmas time, a young girl named Lucinda and her mother are selected to weave a blanket that will be used to cover the figure of baby Jesus in the holiday parade. Unfortunately, Lucinda's mother becomes ill and Lucinda is unable to complete the blanket herself. Disappointed because she has nothing to offer, she hides during the parade until a mysterious woman tells her that any gift from the heart will be appreciated. Lucinda approaches the figure of Jesus with a bouquet of weeds but when she lays them next to the statue, they blossom into beautiful red flowers. This retelling of a story from Mexican folklore, is accompanied by folk-art style illustrations.
