Young Jess, whose best friend moves away, is consoled by a story from her Aunt Millie about the friendship between another young girl, Katie, and Blizzard, Santa’s unusual reindeer. Blizzard, born with the gift of empathic navigation, hears a distant, anguished cry and, following her instincts, discovers Katie living in a new city, friendless and cut off from her one passion – ice skating. Doing everything in her power, Blizzard helps Katie realize her dream — even at the risk of incurring the wrath of Archimedes, Santa’s head elf.
