Orphaned as a teen, Carol Milford grew up in a city in Minnesota. Already a compassionate person, Carol's time studying in college and grad school exposed her to diverse, radical ideas and lifestyles, which she learned to either accept or tolerate. After college, Carol earns a position as a librarian in the state capital city, yet finds the work to be unsatisfying. This is why she agrees when her new husband, a doctor named Will, asks if they can move to his small hometown. However, soon after Will and Carol arrive in the rural town, Carol finds herself immensely disappointed in the scenery and culture. The architecture of the town is ugly and bland, and is decorated to match. Meanwhile, its occupants hold a high level of snooty conservatism, and immediately disapprove of Carol for being a working woman. Because Carol loves her husband and loves to help, she becomes determined to lead a reform for the town by cleaning up the streets and educating the people. However, as Carol attempts to start progressive clubs and tries to make friends, every idea she has is disregarded and disrespected by the town's prominent cliques. Still, Carol persistent, and tries to overcome each obstacle they throw at her, dedicated to inspiring the town to adopt a more accepting and informed culture.
