In Season Six Jack, Amy, Ty, Tim, Lou and Peter struggle to overcome new challenges and attempt to navigate uncharted territory. As the new season begins, Amy is struggling to understand why Ty hasn't said a word about the engagement ring she discovered in his pocket in the Season Five finale. She also has to deal with Ty's acceptance to vet school and the new friends who take him away from her. Working with horses remains the constant in her life and a runaway horse that arrives at Heartland ultimately leads Amy back into the world of show jumping, not just as a rider and competitor, but as a coach. In an unexpected turn of events, a fiery newcomer, Georgie (Alisha Newton), arrives on the scene of Heartland. She is a funny, smart-mouthed, reckless and adventurous 11-year-old who has a penchant for drawing the main characters into situations they wouldn't normally find themselves in. But, as always, the family faces those challenges together, sometimes with exasperation, sometimes with love and always with a healthy sense of humour.
