During the first winter since the restoration of magic, Sunny wants to celebrate Winter Wishday with her friends, but she finds out they all have different conflicting plans. Using the Marestream, a flying recreational vehicle created by the magic of Sunny's lantern, the group travels to visit Hitch's grandmother, then to Bridlewood so Izzy can participate in the unicorns' Wishiehoof Festival, and then to Zephyr Heights so Pipp and Zipp can perform in the city's Wishentine concert. The trip is marred by snowfall that worsens into a blizzard, which Zipp realizes is due to repetition of a unicorn holiday greeting that is actually an ancient spell meant to cause snow. Sunny and her friends return to Bridlewood so Izzy can teach the unicorns a spell to stop the blizzard, then reach the Crystal Brighthouse just in time to see the Wishing Star project their cutie marks into the night sky. Even though they have no gifts to exchange, Sunny is content to have had a chance to spend the holiday with her friends and share in their traditions.
