Britain's prison system is buckling, and this film uses footage shot by inmates themselves to show how. At HMP Birmingham, a minor protest spirals into the country's worst prison riot in 25 years, with hundreds of prisoners loose in the wings, fires burning, and officers pulling back rather than confront the mob. The documentary treats Birmingham as the flashpoint for a wider crisis, tracing chronic staff shortages, record levels of violence, open drug use, and corruption that have left both prisoners and officers at risk. Former officers, ex-inmates, and outside experts describe conditions inside cells and wings that have deteriorated to the point of near-collapse, and question whether the Prison Service can still enforce basic order. The mix of smuggled inmate video and on-camera testimony gives the film an immediacy most prison reporting lacks, letting viewers see the chaos rather than just hear about it. It closes without a tidy resolution, leaving the question of control genuinely open.
