Speed Demon puts a faith-wavering nun at the center of a supernatural thriller set aboard a runaway train, where she must perform her first exorcism before the possessed passenger causes a crash. The Leans Progressive label follows from the film's central framing: institutional Church authority is the obstacle, not the answer, and the protagonist's defiance of entrenched clerical misogyny is positioned as her path to both spiritual and practical victory. Christianity itself is treated positively, which moderates the rating, but the narrative consistently privileges personal conscience over institutional hierarchy. No LGBTQ, trans, or race-swap signals appear. The tilt is modest and driven almost entirely by how the film frames gender and religious authority.
