Sadie Wagner has always been devoted to her family. So when her stepfather is injured and can't work, she decides to leave home and accept a position as a clerk at the mercantile in Goldtree, Kansas. Goldtree also offers the opportunity to use her God-given singing talent --- though the promised opera house is far different from what she imagined. With her family needing every cent she can provide, Sadie will do anything to keep her job.

Thad McKane comes to Goldtree at the request of the town council. The town has been plagued by bootlegging operations, and Thad believes he can find the culprit. After he earns enough money doing sheriff work, he wants to use it to pay for his training to become a minister.

Thad is immediately attracted to the beautiful singer who performs in Asa Baxter's unusual opera house, but when he hears her practicing bawdy tunes, he begins to wonder if she's far less innocent than she seems. And when Sadie appears to be part of the very crimes he's come to investigate, is there any hope the love blossoming between them will survive?
