Cool weather has come to the sleepy Swedish town of Humleby, and Sofie is spending most of her spare time at the village's two stables. On the weekends, she works at her uncle's big trotting stable, and during the week she takes care of two mares at the neighbor's stable. Adam, a guy from her school whom Sofie has a little crush on, is helping her at the neighbor's stable. Sofie's life would be perfect if it weren't for the fact that Speedy, Sofie's favorite horse, is injured. But then one day, Sofie happens to overhear a phone conversation -- and it rocks her world!.
