Season 1
Season One follows the Bartlett-Fleming family, Grandpa Jack, teenager Amy and older sister Lou, as they deal with the ups and downs of running a ranch that's been in the family for generations but is now so deep in debt they're one back payment away from losing it all. After the death of their mother, the girls' lives change forever. Lou returns home from her high-powered job in New York to take over the business of the ranch. Amy realises she has inherited her mother's special horse whispering gift and is determined to keep her mother's dream alive by maintaining Heartland as a horse rescue centre. And Jack just wants to prevent the two girls from killing each other. Thrown into this mix is Ty, the hunky new stable boy; Mallory, the 12-year-old kid next door who never goes home; Scott, the local vet who had a thing for Lou back in high school; and Tim, the girls' estranged father, who has returned to Hudson and wants to reconnect with his family but doesn't know how.
