Two years after conservative activists turned critical race theory into a right-wing rallying cry, the political fight has shifted. The team behind the Peabody Award-winning podcast Southlake tells the story of one family broken apart in the midst of a new anti-LGBTQ culture war, and the high school English teacher caught in the middle.

A mother named Sharla publicly accuses a high school teacher in Grapevine, Texas, of using a graphic novel called “The Prince and the Dressmaker” to convince her child to change genders. Reporters Mike Hixenbaugh and Antonia Hylton set out to investigate the allegation. Sharla’s child, Ren, and Ren’s English teacher, Em Ramser, tell them a different story.

Conservatives are gaining power in Grapevine, fueled by a once-fringe movement that calls on evangelicals to control the seven key “mountains” of American society — including education. A cellphone company with a Christian nationalist agenda heeds that call and sets its sights on winning school board seats in Grapevine, following an example set a year earlier in the neighboring city of Southlake.
