Robertsons main goal in life is to gain promotion to Detective Inspector, the path to which appears to open when he is assigned to oversee the investigation into the murder of a Japanese student. He slowly loses his grip on reality as he works the case, however, suffering from a series of increasingly severe hallucinations. These hallucinations become worse over time, and Robertson descends into insanity. It is ultimately revealed through dreamlike exchanges with Dr. Rossi, his psychiatrist, that he is on medication for bipolar disorder and is wracked with guilt over a tragic accident that led to the death of his younger brother during his childhood. It also becomes clear that Carole, his wife, had left him for another man some time prior to the films events and is denying him access to his daughter, Stacey, developments which sparked his desperate bid for promotion and also led him to start dressing as his wife when off duty in order to keep her close to him.While wandering the streets on such an occasion, Robertson is captured by a gang led by Gorman who are responsible for the murder and badly beaten. However, he manages to kill Gorman by throwing him out a window and is found by his colleagues. Robertson not only misses out on the promotion as a result of the events, but is in fact demoted to Constable and is reassigned to uniform, while rookie Ray Lennox is promoted to Detective Inspector. Afterwards, Blades receives a tape of Robertson apologising. Robertson then prepares to commit suicide by hanging himself, but is interrupted by Mary, a woman whose husband Robertson attempted to save, and her son knocking on his front door. He then breaks the fourth wall and addresses the audience repeating his catchphrase Same rules apply and laughs as the chair breaks under him. ........
