Season 1

The experts race against time to deactivate a grenade that has been discarded in a bin near a gas main on an industrial estate. And they find a hoard of military munitions in a Manchester tower block.

In Liverpool, Sergeant David Podmore is called out to investigate a potential improvised explosive device. In Aylesbury, Sam Jones and Corporal Matt Coogan assess a mortar bomb.

The experts are called to a garage on the Isle of Man, where police believe they have found a bomb-making factory. Meanwhile, on the Wirral, the coastguard has made a disturbing discovery.

The experts take no chances when they are called to smoking chemicals in a property in Chester and search for explosive threats at the Tory Party Conference in Birmingham city centre.
