The arrival of the railroad brings growing pains for Hope Valley, and Elizabeth finds she doesn't have enough school supplies for all of her students. Rosemary helps her settle on the idea of a carnival to raise funds. But also "helping" is Ray Wyatt, the railroad representative, who launches a campaign to replace Elizabeth as Hope Valley's schoolteacher! Meanwhile, Abigail tries to find a balance between good business and what's good for the town, and Frank, Bill and Jack find their hands full after the Tate brothers break out of jail… and begin their own campaign to rob the bank!
Life on the frontier can hand you many tough turns, and so it is for Jack and Elizabeth as they face their very different upbringings, the pressures put upon them by family, rival suitors, and even various criminal counterfeiters and kidnappers in their quest to find their place in this remote and rugged land.
Wounded by the recent death of her husband, Dr. Belinda Simpson (Sarah Jones) arrives in the tiny town of Sikeston to take up the post of town physician. But the residents of the town aren't very trusting of her abilities as a doctor -- mainly because she's a woman.
