A gritty Western standoff between a cop and a murderer.
The Old West finally died in 1980. But we're in Texas, and it's 1978.
This is the story of Grissom Callahan, the last in a long line of
sheriffs. Callahan learned everything he knows from his father and
grandfather, but the ways of the old regime don't prove effective when a
violent killer emerges in their small town. In a single moment of
shaking down an informant, Grissom triggers a chain of events that will
reshape his life and the world of Texas law enforcement.
