Benefit fraud in Britain gets the undercover treatment from reporter Richard Bilton, who uses hidden cameras and on-the-ground investigation to track down people cheating the welfare system out of public money. The film follows fraud investigators as they build cases against claimants faking illness, hiding income, or living off benefits they no longer qualify for, showing the legwork of surveillance, paperwork, and confrontation that turns suspicion into prosecution. Interviews with both investigators and the people they catch give the film its two sides: the taxpayer cost of fraud and the pressures that push some claimants to lie. Statistics on the scale of the problem sit alongside individual case studies, so the numbers stay attached to actual people rather than floating free. Bilton plays it straight, letting the hidden-camera footage and the investigators' own accounts carry the argument about how much fraud costs and how hard it is to stop.
