In the final season of The Hills, Kristin, Audrina and Heidi learn that the people they love the most are the hardest to hold on to. Kristin's summer romance with Justin is fading, but she never really let Brody off the hook, and before they know it they go from friends to friends with benefits. But Brody isn't looking to settle down, and soon he meets a new girl. Audrina finds a fresh start when she starts dating her old friend, Ryan. But no matter how many times she swears him off, Justin is never really out of Audrina's life. No one has changed more than Heidi. Because of her cosmetic surgeries, Heidi has to endure the disapproval of her mother and friends. And a year into their marriage, Spencer is more distant from his family and friends than ever before. The Hills may be coming to an end but it's not over until it's over, and the end is just beginning.
