Boyden and Slater are on a surveillance operation to target a burglar aiming to hit a computer design factory. However, they are distracted, and the op goes wrong. Meanwhile, Stamp and Keane stop a driver with a large quantity of goods in his van. Suspecting that they are the proceeds of the robbery, Boyden arrests the suspect, only to discover the only stolen property was five computer rams worth around £500 each. Slater's informant then comes up with some useful information.
