When Calls the Heart follows the adventures of a young teacher accustomed to her high-society life. She receives her first classroom assignment in Hope Valley, a small town in Western Canada. There, life is simple - but often fraught with challenges. Elizabeth must learn the ways of the Canadian frontier if she wishes to thrive in the rural west on her own but she soon learns that friendship and community are the source of love and life.
In Season Six, the town of Hope Valley adjusts to the changing times – while still maintaining the small-town bonds that connect them. Now a single mother, Elizabeth Thornton (Erin Krakow), Hope Valley’s beloved schoolteacher, navigates life alone when her husband is suddenly killed on duty. Other central characters include Rosemary Coulter (Pascale Hutton), the town’s loveable busybody once described as 'part Broadway showgirl, part Frontier woman', and her patient husband, the upstanding businessman Leland Coulter (Kavan Smith). Sheriff Bill Avery (Jack Wagner) works hard to protect the town and to cement his position as Hope Valley’s ultimate authority, and Dr Carson Shepherd (Paul Greene) keeps Hope Valley healthy all while negotiating his own personal challenges in life and love. New to the community are Mountie Nathan Grant (Kevin McGarry) and mysterious gambler Lucas Bouchard (Chris McNally). Meanwhile, Elizabeth will continue to teach the children of Hope Valley – and although there are potential suitors, the only relationship she is focused on is the one with her baby.
