Whilst out on a crime prevention sweep, Spears visits a local building society, only to be caught up in an armed robbery. Smithy tries to stop the robbers as they make their escape and is also taken hostage. As SO19 units surround the building, Conway and Chandler arrive to negotiate with the two robbers, Dwight and Rollo. A tense stand-off ensues, and Smith realises the men are ex-soldiers, and that they had help from one of the bank employees. When Rollo shoots Dwight during an argument, Chandler orders SO19 to storm the building despite Conway's objections, putting Spears at further risk.
