During a short stopover in Kirby Gap, Kansas, West and Gordon decide to take part in a town-wide celebration sponsored by Amos and Eugenia Rawlins, local ranchers. In the midst of the festivities a shot rings out and, though the culprit seemed to be aiming for local banker Roger Creed, it's Mr. Rawlins who falls dead. The agents pursue the killer and lay hands upon Lucius Brand, who is subsequently convicted of the crime. Mrs. Brand, however, is convinced of her husband's innocence; the agents find themselves uncertain of the truth and decide to do a little investigating of their own.
