A retired policewoman rejoins the force with the explicit goal of exposing what she believes is wrong inside it, then spends four months back on duty wearing hidden cameras. She has no crew and no producer standing beside her, just the badge and the footage she smuggles out after each shift. What the cameras catch is not dramatic corruption but something more mundane and, the film argues, more corrosive: officers speaking to members of the public with contempt, calls left unanswered, incidents logged and then quietly dropped. Dispatches assembles her secret recordings into a single account of a serving officer watching her own colleagues from the inside, without the usual buffer of official access or approved ride-alongs. The film does not chase a single scandal; it tracks a pattern across four months of ordinary shifts, letting the accumulation of small moments make the case. She set out hoping to change the culture she rejoined to document. The footage suggests she mostly succeeded only in filming it.
