A small, quiet (fictional) story of a 90-year-old (well played by 91-year-old Harry Dean Stanton in his last role before his recent death) who goes about his very quiet days in a some small town in the US southwest, exercising, wandering into stores and a diner, watching tv,  drinking at a bar, occasionally, and reluctantly, talking to people, etc.  Plot-wise, nothing much happens, but that’s not the point here.  This is primarily a meditation on life from the perspective of nearing the end of it.
