This season, the characters of Heartland will find they have to return to their roots in order to move forward. Amy (Amber Marshall) will reach a new level of horsemanship and this greater connection with horses will ultimately lead her to a better understanding of the people in her life. Her sister, Lou (Michelle Morgan) discovers the sacrifice and reward of becoming a working mother, while venturing into home-renovation territory with her husband, Peter (Gabriel Hogan) as they take on transforming the Heartland Dude Ranch. Ty (Graham Wardle) will realize that in order to move forward, both in his relationship with Amy and his goal of becoming a vet, he must literally move out of the loft. Tim (Chris Potter) will seek out his long lost son and work on building a relationship with him, while Jack (Shaun Johnston), as always, remains the rock of Heartland, tirelessly keeping the family together through thick and thin.
