The Horseland gang is excited to go on the Twilight Trek, an annual outdoor campout during the course of which horses and riders are expected to bond. Calypso has a saddle sore, however, that prevents her from being ridden. Chloe, who is also unable to go due to a cold, offers to let Molly ride Chili instead. The two initially don't get along, but become friends after a close encounter with a bear.
