It is 1918, and sixteen-year-old Hattie Brooks, who has been shuttled among relatives for as long as she can remember, is currently living in Arlington, Iowa with her Uncle Holt and Aunt Ivy. Hattie's best friend, Charlie Hawley, has enlisted to fight in the war. Although she believes Charlie is sweet on someone else, Hattie considers him a "good chum," and writes to him frequently. Unexpectedly, Hattie learns that an uncle she never knew has died in Montana and left her his claim of three-hundred-twenty acres. Without hesitation, she jumps at the chance to finally make a place of her own.

In Wolf Point, Montana, Hattie is met by her uncle's friends, Karl and Perilee Mueller and their children Chase, Mattie, and baby Fern.

Their lawless activity is an attempt to intimidate Karl Mueller, because he is of German descent.

Hattie struggles to understand how anti-German sentiment because of the war can extend to innocent people like Karl and his family. She receives a visit from Traft Martin, head of the Council of Defense, and her confusion deepens. Traft helps Hattie clear her fields and invites her to a dance. Although he does chide her about her association with the Muellers, Hattie is drawn to the handsome young man. Hattie receives a letter from Charlie, who is impatient to face the enemy in France. She also hears from Uncle Holt, who says he has been sharing her letters to him with the editor of The Arlington News.
