Promise

Promise is a horse owed by Lisa Stillman that Amy is asked to help cure.

Promise will not let anyone ride her. (Until Amy works her magic). She was originally owned by a visually impaired rider whose gentle treatment led the horse to refuse to be saddled or ridden by anyone else. The original owner never used a saddle, preferring to ride bareback with just a halter. Amy works with Promise after having visited that original owner in the hopes of getting to the bottom of her volatile moods and uncooprative nature. Val Stanton claims Promise has been drugged into compliant docility when Amy demonstrates her change in behaviour at an Open House that Lou has arranged at Heartland. Amy protests that she would never drug a horse; Lisa shows up in time to confirm Amy's assertion. Lisa further declares that Amy has a very special gift with horses.
