After Miradero Mel, the town's weather-predicting pig, forecasts that this winter is going to be one of the harshest Miradero's had in decades, Lucky and her best friends, Pru and Abigail, are excited to see what kind of adventures they can have in the snow. Their excitement quickly shifts to concern for the townspeople, who might not have enough food to last the season, and for Miradero's animals, like Lucky's wild stallion Spirit, who has a new foal in his herd. Will they be able to survive the worst that winter has to offer?

The cold winter winds are also the winds of change at home for Lucky and her single father, Jim. It seems everyone has an opinion about Jim's marriage prospects. But Lucky likes their new life just the way it is. She isn't ready for a new mom....But what if her dad is ready for a new wife?

Lucky's first winter in Miradero promises to be one that she, her best friends, and Spirit will never forget!
