When Ty's father, Brad, makes an emergency stop at Heartland with his truck, Amy is horrified to discover what he's transporting. Inside the trailer are seven dehydrated horses, crammed in the rank, stifling conditions. While the Heartland team works to revive the animals, Amy discovers that Brad -- who had never supported Ty's work at Heartland -- is willing to take a stand against his company management in order to prevent the return of the horses to unfit owners. As the horses slowly recover at Heartland, Amy witnesses another miraculous healing -- between Ty and his father.
