In 1899 in rural southern Texas, girls were expected to learn to keep house, make fine embroidery and cook for their families. Calpurnia Virginia Tate, known as Callie Vee, feels this is most unfair and would much prefer to spend time with her grandfather exploring nature and learning about Charles Darwin. She would like to have the same opportunities for an education and a paying job as her 6 brothers do. Her parents disagree of course. Only her grandfather understands and it is his interest in her and his sense of humor which save the day for both of them.
