The sixth series of Heartland continues to follow the lives of sisters Amy and Lou Fleming as they experience the highs and lows of life on the ranch. Heartland is not like any other ranch – it is a horse ranch with a special mission of treating troubled or neglected horses and finding them new homes, and Amy Fleming has inherited her late mother’s uncanny ability to work with, understand and help heal these horses. In Series Six Part One, Amy and Ty continue as a couple, but the weight of the “almost-proposal” takes its toll with touching and humorous results. Lou and Peter’s new home turns into a renovation nightmare which results in a tragic and potentially fatal situation. Jack’s European vacation did not work out as well as he leads Lisa to believe, and a newcomer, an 11-year-old runaway by the name of Georgie, becomes a new fixture at the Heartland Ranch.
