Antonia Ford Willard (July 23, 1838 – February 14, 1871) was a volunteer civilian spy for the Confederate States Army during the American Civil War.

[1] As Union forces occupied the Fairfax region in mid-1861, Ford circulated among the officers and garnered valuable intelligence about troop strengths and planned movements, which she passed along to Brigadier General J.E.B.

She was accused of playing a prominent role in the capture of Union general Edwin H. Stoughton, but Colonel Mosby and others later denied her complicity, and no evidence of her guilt could be found.

The screenplay, adapted from Karla Vernon's The Spy in Crinoline and numerous primary sources, intersperses dramatic sequences shot on-location in Fairfax County, Virginia, with period images, narration, and interviews with historians.

Directed by Bert Morgan, it stars Emily Lapisardi as Antonia Ford, Gregory Labenz as Joseph Willard, Becci Varga as Laura Ratcliffe, and Joe Cain as General J.E.B.
