Four women led by Donna Fuller have started a Westward Temperance Movement. After destroying a saloon in a town they leave via a wagon. On a downward slope the horses run away and Donna cannot control them. Charlie and Alonzo Galezio, a winemaker on the wagon train, spot them while on a grape picking trip. After they stop the horses, Alonzo and Donna spot each other with a strong attraction between them. He decides to propose to her which she is nearly ready to accept when Alonzo says he does not drink distilled spirits. However, when she overhears Alonzo and Charlie talk about making wine (fermented not distilled) she decides to reject him but refuses to say why. The women decide to put on a temperance rally which gets out of control resulting in the destruction of Alonzo's barrels of wine.
