For generations the greatest perceived threat to the West has been nuclear. But in actual fact, it is a far less sophisticated piece of weaponry, comprising of just a stolen vehicle and a boot-load of homemade explosives.

Crude and deadly this threat is the car bomb. From the team behind the critically-acclaimed Cult of the Suicide Bomber comes this new two-part series presented by ex-CIA operative Robert Baer.

Baer charts for the first time the evolution of this simple, but most deadly of insurgent weapons, travelling through London, South Armagh, Oklahoma, Sicily, Iraq and New York, for this major exploration into the methodology of terrorism.
