Young Swedish-American Katrin "Katie" Holstrom leaves her family farm in Minnesota, headed for nursing school. After her tuition money runs out, she is forced to take a job as a maid in the home of Congressman Glenn Morley. Holstrom endears herself to the genteel Morley, and begins to show a surprising aptitude for politics herself. She launches a campaign for Congress, and, as right-wing reactionaries plot against her, a romance develops.
