Carrie is a big-city teenager whose life is turned upside down when she moves to a horse ranch in Wyoming to live with her father. But everything changes when Carrie meets Flicka, a wild, jet-black mustang who's just as free-spirited and strong-willed as Carrie. The two form a special bond and Carrie opens her heart to her father and a handsome, local boy, but when a jealous rival puts Flicka's life in jeopardy, Carrie must do whatever it takes to save her best friend.

A raw, powerful story of two young men, a Wyoming ranch hand and a rodeo cowboy, who meet in the summer of 1963 sheepherding in the harsh, high grasslands of contemporary Wyoming and form an unorthodox yet life-long bond--by turns ecstatic, bitter and conflicted.
