While the synopsis itself doesnt tell us a whole lot more than the original does about the actual episode, it does reveal that we will be returning to working with the Cutie Map as the season chugs along. That season 5 aspect has been largely absent for all of season 6. Usually themes don't cross over seasons.
Head on down below if you want to read the updated synopsis
Pinkie Pie and Rarity are called to Canterlot by the map to solve a friendship problem. They discover a father and daughter whose relationship is strained as they struggle to keep their restaurant open.
Thanks to Vincent for the heads up
