Detective Chief Inspector Colin Sutton is tasked with reviewing Operation Minstead, an eleven-year, multi-million-pound enquiry to catch the `Night Stalker'.

Colin presents his review findings to DCS Hamish Campbell and suggests a strategy called `Minstead Lite'. But Hamish wants Colin to stay on to see this new approach through.

The Force Tasking Group must decide whether to fund Colin's high stakes gamble. Not only is it expensive, but there's absolutely no guarantee it will work.
