At the time of a paralyzing drought in the West we discover a girl whose father and two brothers are worried as much about her potential future as an old maid as they are about their dying cattle. For the truth is, she is indeed a plain girl. The brothers try every possible scheme to marry her off, but without success. Nor is there any sign of relief from the dry heat, when suddenly from out of nowhere appears a picaresque, sweet-talking man with quite the sales pitch. Claiming to be a "rainmaker," the man promises to bring rain, for $100. Rain does come, and so does love.
