Nora Mahler leads a perfect life. With her two teenage children, Simon and Clea, and her husband, she thrives on running the family horse ranch on the banks of the Missouri until Simon is killed in a riding accident. Nora's husband Neal sends the horses away, and when Nora refuses his orders to sell the farm, he moves to Chicago, taking Clea with him. Soon after, Ozzie Kline, a horse wrangler who has longed for Nora since they were teenage lovers, helps Nora and her mother rebuild their farm. Alongside Ozzie, Nora finds a happiness she never knew with her husband and wonders, "What if we had the opportunity to love each other again?"--until Neal returns to claim what he considers his.
