The series followed the adventures of Sara, a 13-year-old girl growing up in the American West, as she discovers her true identity as a princess in hiding from another realm. A talking horse, Wildfire, summons Sara through her magic amulet, and transports her across dimensions to her real home in Dar-Shan. Sara joins with her friends, a sorcerer named Alvinar, a young boy named Dorin, and a cowardly colt named Brutus to confront her wicked aunt, the evil witch known as Lady Diabolyn. Diabolyn feels Queen of Dar-Shan is her rightful title. She was stepsister to Queen Sarana, Sarah's mother, whom she always considered weak and unfit to rule. When she was just a baby, Princess Sara was saved from the clutches of Diabolyn by a mystic horse named Wildfire, who took her away from the planet Dar-Shan and deposited her in Montana (the state, not the planet). But though Wildfire won this battle, Diabolyn had won the war, and the sorceress now reigned supreme over the princess' homeworld. Twelve years later, when Sara was ready to fight evil, Wildfire brought her back to Dar-Shan to bring down her nemesis and regain her throne. The two heroes were helped by a boy named Dorin, another horse named Brutus, and a farmer named Alvinar. Sara's father, John, and his friend Ellen provided moral support from back on planet Earth.
