ring training, Judy becomes fast friends with the other women in her unit--Stacy, Bernadette and Mary Alyce--who all come from different cities and circumstances. Under Second Officer Charity Adams's leadership, they receive orders to sort over one million pieces of mail in England, becoming the only unit of Black women to serve overseas during WWII.

The women work diligently, knowing that they're reuniting soldiers with their loved ones through their letters. However, their work becomes personal when Mary Alyce discovers a backlogged letter addressed to Judy. Told through the alternating perspectives of Judy, Charity and Mary Alyce, Women of the Post is an unforgettable story of perseverance, female friendship and self-discovery.
