Gloria Mullins has been sent to her home town of Grimley to determine the profitability of the pit for the management of British Coal. She also plays the flugelhorn, and is allowed to play with the local brass band after playing "Concierto de Aranjuez", affectionately known as “Orange Juice” by the characters, with them. The band is made up of miners from whom she must conceal her purpose. She renews a childhood romance with Andy Barrow, which soon leads to complications. Andy is bitter about the programme of pit closures and determined to fight on, but he is also realistic about the circumstances and predicts a 4-to-1 majority for closure and redundancy. When Andy realises that Gloria is working for management, he accuses her of naïvety for thinking that the Coal Board is considering whether the pit has any viable future and argues that the decision to close Grimley would have been taken years earlier. It is later revealed, during a confrontation between Gloria and the management of the colliery, that the decision to close the colliery had been made two years previously, and that this was to have gone ahead regardless of the findings of her report; the report was simply a public relations exercise to placate the miners and members of the public sympathetic to their plight.
