Now, eighteen years after she left her home town, her sisters insist that she return to help care for their widowed mother. There she faces a rude awakening in the shape of an insulting older sister, an intractable parent and worst of all, the apparent total indifference of Kenny Kronek, the neighbor she mercilessly taunted all through high school who is now a handsome divorce. Discovering that Kenny's adored daughter Casey is now a promising country-music talent, Mac assumes the role of her mentor. As their mutual concern for Casey transforms Mac and Kenny's relationship, the pampered star learns to treasure family and community. But can these newfound commitments survive back in Nashville, in the realm of superstardom?
