My wife and I watched this at home on DVD from our public library.
It is set in an unspecified place at an unspecified time, it could even be a fictional parallel universe. A running theme is that water is very scarce, crops are drying in the fields, rain is badly needed, towns are becoming ghost towns.
British actress Gugu Mbatha-Raw (I love that name) is the lead character Ruth who must go on the run because of some incidents resulting from her "gifts" that we eventually learn run in the women of that family, passed on to each new generation. We meet both her mother and her young daughter.
It is hard to say what the story is really about. It isn't clear what their "powers" can accomplish, but we mostly enjoyed the movie as an entertaining 100 minutes. It appears that the ending set up for a sequel and in fact I read that Amazon has begun to make a series that probably will be available on Amazon streaming.
The filming was done in New Mexico and the small, dusty town is Estancia. Online maps street view clearly show the Blue Ribbon Bar, for example.
Pretty good movie, if you don't expect too much.
