A CI5 agent is murdered, leading to the discovery of a man who is dying as a result of plutonium poisoning. This links CI5 to a further plot involving the imminent explosion of an A-bomb at the same bowling alley. It's left to Bodie and Doyle to try and de-activate the fuse before it takes them and the whole of London with it.
