Home on the Range

She flees on her mustang Salsa, and ends up - with saddle bags of stolen money and a couple of bullet wounds - at Whispering Range, home of a New Mexican horse whisperer. The old man calls her "Cassie," and although she doesn't think that's her name, since she can't remember who she is, she agrees that he can call her "Cassie" if he wants to.
The only thing she can remember, and that because of recurring nightmares, is that at least two men are trying to kill her.
