In 1987, a videotape depicting consensual sadomasochistic sex between men in the north of England reached local police and triggered what became known as Operation Spanner, one of the largest and most expensive vice investigations in British history. The film follows the men who were arrested, prosecuted, and in some cases imprisoned for consensual acts performed in private, tracing the case through to the House of Lords ruling in R v Brown, which held that consent was no defense to the charges. Interviews with several of the men involved recount police raids, media coverage that named and shamed them, and the personal cost of a case that reshaped English law on consent and bodily autonomy. Archival material and courtroom detail sit alongside first-person testimony, giving weight to a case still cited in debates over what the state can regulate inside a bedroom. The film treats its subjects as witnesses to their own prosecution rather than case studies, letting them describe what the law cost them.
