Amy Fleming has a rare gift for calming traumatized horses, a skill her family's struggling Alberta ranch badly needs as debts pile up and grief over her mother's death still lingers over the Heartland property. Amber Marshall plays Amy with an unforced gentleness that anchors the show's long run, opposite Graham Wardle's Ty Borden, whose own rough past mirrors the animals they rehabilitate together. Shaun Johnston's gruff grandfather Jack Bartlett supplies the ranch's moral backbone and most of its dry humor. Modest and unhurried, it's a family drama that finds real stakes in mending both broken horses and broken people.
