To the surprise of resident Sgt. Sullivan, Mattie arrives at Kilcommon Garda Station as the new Sergeant. Sullivan is preparing for the arrival of a TV crew who plan to film a hard-hitting documentary. After Mattie initially disappoints the TV crew with banal tourist trivia he takes them on a helter sketer, high speed tour of the locality which leaves them shaken but unimpressed. When Mattie tells the locals that the crew are leaving there is dismay that the town will lose out on the publicity. At Mrs. Early's prompting Mattie plans a fake post office raid, staged by Mrs. Early's nephews to impress the TV crew. Events take a turn for the peculiar when real armed robbers show up instead of the fake ones. Unaware of this change, Mattie proceeds to put on a 'bit of a show' for the filming TV crew who go 'live' with the raid. After shots have been fired, Mattie triumphs and captures the criminals. Back in the Carr's pub Sgt. Mattie receives a hero's welcome, only to discover from Mrs. Early that the robbers were in fact real. Their plan to keep it quiet soon becomes unstuck.
