Welcome back to Promise, Texas, a ranching community deep in the Hill Country. It's a good place to live and raise a family––and a good place to visit. Yes, there's a secret or two hidden beneath Promise's everyday exterior, but what town doesn't have its secrets?

They call her Dr. Texas. She's Jane Dickinson, a newly graduated physician from California who's working at the Promise clinic–but just for a couple of years. They call him Mr. Grouch. Cal Patterson was left at the altar by his out–of–state fiancée, and he's not over it yet. Too bad Jane reminds him so much of the woman he's trying to forget!
