The attempted assassination of the first female president of the United States during her inauguration speech in 2024 leads to a revolution. Fifty years later, Matriarchy follows Althea Hayworth and Michael Nolan's journey to understanding the ways in which their matriarchal society has demonized heterosexuality and male-female interactions, ousted men from all positions of political power, and made men into second-class citizens. As Althea learns the untold history of the world from Michael, she questions whether the matriarchy is the utopia that she has been taught to believe it is and if marrying Felicity, her fiancée, is the best decision. As she struggles with her choices, she grapples with a group of men's rights activists fighting for their rights, a tyrannical mother who refuses to tolerate her daughter's newfound voice, and a court case that leaves her and Michael wrestling with a justice system that assumes the guilt of any man who walks into it.
