Young mum Courtney Slater is dragged screaming from her car at knifepoint in a terrifying early evening robbery in a quiet residential street. But Courtney and her boyfriend are determined not to let the criminals get away with it. Using an app on their mobile phones, they recover their car and help police track down the robbery gang and bring them to justice.

We also see how an intruder alarm with 360-degree vision is protecting businesses in rural locations, including a garden centre in Northamptonshire, and how new interactive police line-ups are helping improve the accuracy of eyewitness identification.
