Sarah, Alma, Molly, and Zoey are assigned to doing musical kur for an upcoming competition, but Calypso struggles with learning the routine. Worried they will mess up during the competition and embarrass her and Pepper, Zoey attempts to get Molly to drop out by convincing her that Sarah and Alma plan to drop her from the routine anyway. Unfortunately, Molly takes it as a sign nobody wants her around Horseland anymore and plans to leave the ranch forever. Then Sarah and Alma find out what Zoey did, and even though the show is about to start, they go find her, compete in the show (in which Calypso finally learns the routine), and teach Zoey a lesson.
When the new girl, Sarah Witney arrives at Horseland, Chloe and Zoey are eager to meet a fellow wealthy girl. However, Sarah just wants to make friends with the nice people (and horses) of Horseland, and so does her horse, Scarlet. The rest of the gang judge Sarah before they meet her because she's rich, after which Sarah decides that maybe she just doesn't belong at Horseland. Eventually, the others decide to give her a chance and everyone becomes good friends.
lma Rodriguez thinks she is too good to practice for the upcoming Huntingfield Downs horse show, because she feels she is the 'best' jumper at Horseland. However, the course is changed at the last minute and Horseland doesn't do so well in the show. In the end, Alma learns a lesson about the importance of trying her as well as the importance of practicing. Eventually, Chloe Stilton wins the show for Horseland because she actually practiced the routine.
