Recently separated parents Tracie (Fisk) and Rick (Rogers) spend every other holiday with their young daughters Harper and Ava. But this Christmas, the girls have only one thing on their wish lists — to spend Christmas with both Mom and Dad at Tracie’s family farmhouse. The temporary reunion will be no walk in the park for Tracie and Rick, but perhaps this Christmas gathering can help rekindle the lost romance between the two and make their daughters’ greatest wish come true.

Littlefoot and the gang meet a shy newcomer, Ali, but the pleasantries stop there. There's a dire environmental theme to this third sequel in the series, in which the world's weather changes beyond the Great Valley, and what had been dry land is now a "land of mists." The shift brings new creatures who push out older inhabitants, and Littlefoot sees these radical changes for himself when he has to venture into the area to find a medicinal flower for his sick grandfather. While the animation is slow and contained the way direct-to-video cartoon releases often are, the story is sound and the now-familiar characters are memorable.
