The Gray House, an upcoming American historical television drama produced by Kevin Costner and Morgan Freeman, will open Monaco’s 63rd annual Monte-Carlo Television Festival in June.

The TV limited series about a female spy ring during the Civil War tells the hidden-history tale of four Southern women — a Virginia socialite and her mother, a formerly enslaved Black woman and a high-end prostitute — who served as key espionage agents for the Union. SANDRA JAMES-YOUNG will play the role of Lavinia.

The foursome are credited as unsung heroes who helped end the nation’s brutal cleavage in 1865. Mary-Louise Parker, Amethyst Davis, Daisy Head and Ben Vereen lead the ensemble cast.
