Richard Dawkins investigates the rapid growth of faith schools in Britain, where roughly 7,000 publicly funded schools, one in three, now carry a religious affiliation. He visits classrooms and interviews head teachers, pupils, and religious educators across Christian, Muslim, and Jewish institutions, questioning how creationism, segregated worship, and doctrinal teaching sit inside a state-funded system meant to serve all children. The film tracks the government's push for "free schools," which hands more control over curriculum and admissions to religious groups, and Dawkins presses ministers and school leaders on whether taxpayer money should underwrite religious instruction at all. He argues that separating children by faith from an early age entrenches division rather than tolerance, and confronts teachers who defend the practice as parental choice. Interviews with education researchers and secular campaigners balance the picture, but Dawkins keeps returning to children themselves, asking what they are being taught to believe before they are old enough to question it.
