Season 5 follows sisters Amy and Lou Fleming and their grandfather, Jack, through the highs and lows of life on a horse ranch. At the end of Season Four, Amy and Ty were finally feeling their way back into each other's lives after a difficult break-up. There was also a new addition to the Heartland family when Lou and Peter had a beautiful baby girl. And Tim was struggling to reconcile his feelings when he learned of a son (Shane) he never knew he had. In Season Five, Amy reaches a new level of horsemanship that sets her down a freeing path. It's all about going back to her roots and getting in touch with her special connection to horses in a deeper, more confident way. This greater understanding of horses leads to Amy better understanding people, and opens her up to greater opportunities. Ty realizes that in order to move forward with his life and his relationship with Amy, he has to make some tough decisions. Lou grapples with the realities of motherhood and the possibility of going back into the workforce when money becomes tight. Tim seeks out his long lost son to establish a relationship and must figure out a way to tell his daughters they have a brother. Jack will remain the rock of Heartland, gently (and sometimes not so gently) helping his family deal with the ups and downs they experience in their lives. Jack also takes some risks and learns to face his own fears.
