Kate Saxon inherits the Blue Goose mine in Colorado, and arrives as rioting miners battle a sheriff’s posse. Once the disturbance has been quelled, Kate improves wages and working conditions. With the encouragement of old “Bells”, the mining engineer, a friendship quickly develops between Sheriff Tom Baxter, a wealthy cattleman, and Kate. Consequently, when women suffragists urge Kate to run for sheriff, she is initially reluctant to oppose Tom, but finally accepts and wins the election. Tom decides to test Kate’s mettle by leading her to believe that he bribed voters. His arrest convinces him that Kate is serious about her new job, and he admits that the story was false. Although Kate frees Tom, she does not forgive the lie. As she rides away, Tom follows her and they are caught in a cattle stampede after labor agitator Tremble dynamites the reservoir. They race for their lives, and when all danger has passed, Tom professes his love for Kate. She spurns him until old Bells finally brings about a reconciliation.
