On Christmas Eve, Comet goes missing, and Santa calls on a child to save the night. With a tiny elf named Tinker, the child follows hoofprints across the North Pole. After searching the workshop, cookie room, and candy cane fields, a faint jingle is heard in the Snowflake Forest. Comet is found scared but safe and gently led home. Santa cheers, the reindeer line up, and Christmas is back on. As the sleigh takes off, Santa calls out a warm holiday thank-you to the young hero who saved the night.
