At the end of Season Three, dreams and opportunities pushed everyone in different directions. Amy went on the Ring of Fire tour, Ty hit the road to see a bit of the world, Lou moved to Dubai to start a new life with her husband, Peter, and Tim chased big money on the California horse racing circuit. In Season Four, people drift back to Heartland, craving the familiarity of home and family only to discover that everything seems to have changed. After the blush of first love in Season Three, Ty and Amy's young relationship will blossom and mature, but only after they face up to a misunderstanding about what happened while they were apart. Lou is torn between her new life in Dubai and home. She's still madly in love with Peter, but Dubai is not an easy place to live and she's intensely homesick. Tim will return with substantial winnings and a new love interest. As always, Jack remains the rock of Heartland who tirelessly keeps the family together through thick and thin.
