The film follows Officer Sandra Perron, who at the height of a brilliant career with the Armed Forces, resigns unexpectedly. The brass launch an investigation that revs up when a photo circulates of Sandra in uniform tied to a tree apparently unconscious. This was not how the career of the first female officer in the Canadian infantry was supposed to end. Besieged by journalists, struggling to adapt to civilian life, and pursued by the investigation, she denies that she was the victim of abusive treatment and refuses to press charges.
