"He's been shot, he's been shot!" Gunfire breaks the silence of a summer's evening in Woodford, East London.

The victim lies bleeding as the assailant speeds off in a waiting car. The same vehicle is used to flee a burglary in Kent the evening prior. A month before the shooting, a door is forced open at an art museum in Geneva, Switzerland. The thieves escape with over 拢2.5m worth of artefacts.

A journalist, a forensic psychiatrist and a former police detective delve into an almost six-year investigation. They look at the evidence that was left behind after the near-fatal assassination attempt and examine how police linked it to the robbery of items including a priceless Ming vase from a museum in Switzerland.
