Take a trip to the rolling foothills of the Rocky Mountains for an all-new season of this gorgeous and heartwarming family drama based on the beloved Scholastic book series by Lauren Brooke. HEARTLAND: THE COMPLETE FOURTH SEASON follows life on the Heartland ranch as Amy Fleming (Amber Marshall) and her oldest sister Lou (Michelle Morgan)) continue to deal with the challenges of running the ranch that has been in the family for six generations. 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 has inherited her late mother's uncanny ability to work with, understand and help heal those horses and, across 18 FOURTH SEASON episodes, she does just that.
