Set against the stunning vistas of the Alberta Rocky Mountains, Heartland is a sprawling family drama that follows the Fleming sisters Amy (Amber Marshall) and Lou (Michelle Morgan), through the highs and lows of life on a horse ranch. As Lou adjusts to her new life in the country, Amy has troubles of her own as Ty (Graham Wardle) returns and competes with Caleb (Kerry James), the new stable hand, for her heart.
