Deputy U.S. Marshal Raylan Givens is a 19th century-style but modern-day officer, who enforces his brand of justice which puts a target on his back with criminals and puts him at odds with his bosses in the U.S. Marshals Service. As a result of his having eagerly shot a Miami fugitive in a "justified" shooting in his South Florida assignment, he gets reassigned to the district covering his rural Eastern Kentucky mining hometown of Harlan County.
