Eighty-nine-year-old Isabelle McAllister has a favor to ask her hairdresser Dorrie Curtis. It's a big one. Isabelle wants Dorrie, a black single mom in her thirties, to drop everything to drive her from her home in Arlington, Texas, to a funeral in Cincinnati. With no clear explanation why. Tomorrow. Dorrie, fleeing problems of her own and curious whether she can unlock the secrets of Isabelle's guarded past, scarcely hesitates before agreeing, not knowing it will be a journey that changes both their lives.
