Missie LaHaye bids a reluctant goodbye at the grave of her late husband Willie, who died two years previously in the line of duty as the sheriff of Tettsford Junction. Even after giving up her job as the town schoolteacher, Missie has found running the ranch on her own overwhelming, so she has resigned herself to letting her son Jeff and his new bride take control of it jointly with her brothers Aaron and Arnie.
Missie and her ten-year-old son Mattie travel back to her hometown to live near the farm of her parents, Clark and Marty Davis. She goes back to teaching school. At her first Sunday service, Missie and Mattie learn from the attractive—and single— Pastor Joe that an “Orphan Train” with homeless children in need of good homes will soon arrive from the Children’s Aid Society of New York. Outside the church, Clark introduces Missie to sharp-tongued biddy Mrs. Pettis, who disdains the orphans as "ragamuffins." At the same time, Missie catches the eye of a passing horseman: bachelor Sheriff Zach Tyler, another target of Mrs. Pettis’ vitriol. Claiming that Zach is not a godly man, Mrs. Pettis passes her judgment on him, implying he has a shameful past on the wrong side of the law.
