Rainbow Dash is eager to ride the Wild Blue Yonder, a famous roller coaster in Las Pegasus, before it permanently closes.

Applejack agrees to take over her classes at the School of Friendship if she chaperones Granny Smith and her elderly relatives for their annual Las Pegasus vacation, strictly instructing Rainbow Dash to never let them overexert themselves or leave her sight.

However, the grannies sneak off while Rainbow Dash discovers the coaster's long waiting line, forcing her to spend most of the day following them and interfering with their exciting activities, much to their annoyance.
