Horsenapped Stevie, Carole and Lisa are best friends and horse-crazy members of The Saddle Club. The three are looking forward to the combined-training event at Pine Hollow Stables, when all riders will compete in dressage, cross-country and stadium jumping. It's a horse lover's dream! When snooty Veronica blames her bad performance on her horse, Garnet, and storms out of the ring, Carole follows, fearing Veronica's threat to giveaway her horse. But horse and rider have disappeared. Later, when Lisa finds a $10,000 ransom note in the stall, the possibility becomes all too clear: Garnet has been horsenapped! Who would have thought that The Saddle Club girls would ever feel sorry for Veronica? The girls resolve to catch the horsenappers and soon find themselves in a daring escape that puts all their horse-riding skills to the test. Pack Trip Carole, Stevie and Lisa are thrilled when they get a call from The Bar None Ranch. Kate has an offer for them: Would the girls like to go on a pack trip in the mountains? The answer is an enthusiastic yes! When they meet the other riders, they couldn't be happier. Lisa feels instantly drawn to Seth, while his fun-loving sister Amy seems to be a perfect pal for Stevie. Another boy, John, is as serious and horse wise as Carole. The group hits it off immediately. But first impressions can be deceiving. Amy isn't just high spirited and impulsive, she's downright reckless. As her behaviour gets more outrageous and dangerous, Seth tries to cover for her and puts Lisa in the middle. Can the girls figure out what to do about Amy before her next wild stunt threatens all their lives?
