The year is 1823. Orphaned at birth and raised by an abusive guardian who seeks only to marry her off for money, young Nawi (Mbedu) petitions for entry into the Agojie, led by the single-minded Nanisca (Davis). To defend their people against the oppressive and heavily armed Oyo Empire, the Agojie run candidates through an arduous training program. Nawi proves herself an outstanding, ferocious soldier, though she questions the Agojie rules, which state that no one in their ranks shall marry or have children. As the Agojie prepare for the fight of their lives against both the Oyo and the Portuguese slave traders with whom they are in league, long-buried secrets come to light, revealing harrowing stories of personal sacrifice that will only strengthen the bonds between these unstoppable warrior women.
