"To avoid marrying a neighbor, Sarah Louisa Wheelock disguises herself as a boy and enlists in the Flint Union Greys, a regiment that becomes part of the 2nd Michigan Infantry during the Civil War. Sarah, now known as Neddy Compton, works as a male nurse and entertains the wounded soldiers until her real identity is discovered. But her talent for mimicry brings her to the attention of Allan Pinkerton, head of the Pinkerton Detective Agency. Pinkerton offers Sarah the opportunity to become a woman 'operative.' Her first assignment is to investigate Rose Greenhow, a suspected Southern spy. Suddenly Sarah is plunged into a world of danger and intrigue where the simplest mistake could cost her her life."
