It's 1942, and best friends Mary and Marge leave their teaching jobs behind in Iowa to move to Washington D.C. to work for the FBI. Excited yet apprehensive, neither of them could anticipate the rapid changes the war will bring into their lives.

Arriving at Union Station, they meet Dotty, a quick-witted woman who left her all-girl band in New York City in search of new opportunities. Despite rampant racism, Dotty manages to find a clerical job with the government, thanks to her prized possession - a typewriter.

The three women band together, renting rooms in a run-down mansion that operates as a restaurant and boarding house. Under the same roof lives Natalie, an eccentric artist trying desperately to sell her screenplays and achieve her Hollywood dreams.

As Mary and Marge begin their demanding fingerprint filing jobs at the FBI, they find themselves growing increasingly vulnerable, but also courageous, in the face of a world ruptured by war. The four women couldn't be more different, yet they forge an unbreakable bond confronting rapidly shifting social conventions and opportunities for women.
