In order to keep Riverdale High's basketball legacy alive, Frank and Archie recruit a new player to the team - a quiet farm boy named Reggie Mantle. Tabitha's return to school inspires Toni to start a literary society for Riverdale's Black students. Alice forces Betty to join the River Vixens, and Kevin starts a new job at the Babylonium.
Set in the present, the series offers a bold, subversive take on Archie, Betty, Veronica and their friends, exploring the surreality of small-town life, the darkness and weirdness bubbling beneath Riverdale's wholesome facade.
