The Investigator (1997)

Helen Baxendale (Cold Feet, Friends) stars as Caroline Meagher, who in the 1980's was an up-and-coming stall sergeant in the Royal Military Police. Caroline eagerly accepts a plum assignment with the Special Investigative Branch. But her task - to root out and interrogate suspected lesbians - becomes a nightmare as she gradually awakens to the truth about her own heart’s desire. Based on a true story, this stirring drama tells a shocking tale of intolerance, of private lives invaded and careers destroyed - all carried out in the name of justice when the only crime is love.
