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) and their grandfather Jack (Shaun Johnston), through the highs and lows of life on a horse ranch. Having realized their feelings for each other, Season Three unfolds with Amy and Ty (Graham Wardle) now a couple while Lou builds on her own blossoming romance, bringing interesting developments to their relationship. Ty's interest in helping animals has local vet Scott (Nathaniel Arcand) as his mentor, and Tim (Chris Potter) - Amy and Lou's father - is becoming more of a presence in his daughters' lives and he and Jack are beginning to get along. That is, as well as can be expected.
