Inside three of Australia's maximum security prisons, cameras follow the Immediate Action Team as they raid cell blocks, break up weapons stashes, and manage inmates who slip through the cracks of the system. At Wellington prison an inmate collapses and a search turns up an unauthorized visitor inside the walls. At Dillwynia, a pre-dawn raid and mass strip search expose the routes drugs take into a facility meant to be sealed off from the outside world. When Covid restrictions cut off visitors, the drug supply dries up too, and inmates in withdrawal riot rather than go without. The tension breaks, briefly, around an annual touch-footy match between teams from Wellington and Macquarie, though moving prisoners between facilities for the game requires its own high-alert operation. Officers and inmates both speak on camera, giving a ground-level account of what running and surviving a maximum security prison actually involves, day to day, raid to raid.
