The central story revolves around an autistic bank robber turned protected federal witness (Bruce) who Fraser and Kowalski accidentally expose on TV after he saves a child's life. Bruce's brother is a senior Justice Department official who Bruce believes has always looked out for him. In truth, it was his brother Kevin who instigated the robbery and now needs Bruce out of the way to protect his future career. But how far will he go to achieve this?
In protecting Bruce, Fraser and Kowalski both feel something is not right and as they find out what is going on, Bruce also gradually learns the truth. What is particularly impressive about this episode (and it must be said practically every episode of DS) is not what is said but what is not. The dialogue is spare but still conveys everything the viewer needs to know.
Around the main plot, Elaine is graduating from the Police Academy with her brother officers; Kowalski admits to being fond of Francesca (which is awkward as he is supposed to be her brother and his feelings are anything but brotherly!) and we find out that Fraser was part of a scout-troop as a boy, involving himself, his best friend and the friend's sister - a substitute for the siblings he never had.
The plot builds to a touching finale as Bruce confronts his brother in the woods in driving rain. The dialogue for the scene is almost drowned out but it doesn't matter. A shoot-out ensues in which Kevin has the chance to kill his brother but cannot, blood-ties finally overcoming his greed for power. Fraser, Kowalski, Welsh and Bruce are saved when Elaine's graduating class of police officers come charging over the hill. This may sound rather melodramatic, but is in fact beautifully done. These final scenes are played out to the haunting "Brothers in Arms" by Dire Straits, which complements and enhances the scene to perfection. If this was any other show, the producers would doubtless have backed this scene with something loud and intrusive whereas the musical choices in DS are invariably creatively superb.
The acting honours in this episode must go to Brent Carver as Bruce; he really is excellent and manages to strike exactly the right note of vulnerability overlying a remarkable intelligence.
Imagine Inspector Thatcher sharing the building with two "nutties".
Perhaps that's why she turned off to Fraser.
