Dora is to visit her uncle in the West; she is informed that the boys at the ranch are all anxiety over her coming. In the spirit of fun, Dora determines to masquerade as a spinster. Uncle is in on the joke and shares Dora’s amusement in seeing the shock of disappointment which the boys receive as Dora steps from the stage coach. Jim, the foreman of the ranch, is too good-natured ti show his disappointment and offers to carry the spinster’s grip into the house. By doing so he excites the laughter and ridicule of the boys. Later Jim goes further and teaches the spinster how to ride a horse. Cupid gets busy under the make-up and Dora’s girlish heart begins to beat warmly for the handsome cowpuncher. In spite of the laughter and the ridicule of the boys, Jim is head over heels in love with the supposed spinster. He asks her to be his wife - she removes the disguise and reveals herself to Jim in all her youth and beauty. Jim is at first astonished and then delighted. He takes the lovely Dora in his arms as his promised wife.
