Matthew LaClair, a student at Kearny High School in New Jersey, secretly records his history teacher David Paszkiewicz telling the class that evolution and the Big Bang are not scientific and that non-Christians will burn in hell. When LaClair brings the recordings to the school board, the film follows what happens to both of them: LaClair becomes a target of harassment from classmates and the community, while Paszkiewicz faces a disciplinary process that splits the town. Interviews with students, parents, school administrators, and both the teacher and the student lay out the competing claims about what happened in that classroom and what should happen next. The film uses the actual audio recordings alongside school board meetings and local news coverage to reconstruct the dispute in close detail rather than summarizing it. Underneath the specific incident sits the larger, unresolved argument over religion in American public schools, and the film stays with the human cost to a teenager who became a national news story for doing what he thought was right.
