Abilene gunmen are bent on terrorizing the town of Blue Valley and massacring its inhabitants. They have been hired by local druggist Henry Turner, who has discovered gold beneath the town and wishes complete possession. The gunmen rob supply wagons, burn houses, kill leading citizens and then the gang leader, Brink Fallon, having acquired Rocky Lane's paper, poses as the new deputy marshal sent to bring order. Then the real Rocky Lane shows up in his usual bad mood, and the tide begins to turn.
