Widowed only a year, Longmire is man in psychic repair that buries his pain behind a brave face and dry wit. Struggling since his wife's death and at the urging of his daughter, Cady, Longmire knows that the time has come to turn his life around. With the help of Vic, a female deputy new to the department, he becomes reinvigorated about his job and committed to running for re-election.

Longmire often turns to close friend and confidant Henry Standing Bear for support as he sets out to rebuild both his personal and professional life, one step at a time.
