John Probe is subjected to compu-puncture experiments over the course of months, and augmented with computer circuits printed on to his skull in a sixteen hour operation. On the day that his testing is supposed to start he is instead taken to an RAF base which has been attacked by terrorists. He storms a nuclear blast-proof door, killing most of the terrorists, but is told by the final target that they have been a decoy and that the true purpose of the exercise was to hijack a bomber with a cargo of nerve gas.
An RAF Nimrod is scrambled with Probe on board. He exits the Nimrod at 23,000 feet via the bomb bay doors and digs his hands into the Vulcan bomber fuselage, which he proceeds to rip away. Though he deals with the two terrorists on board one of their bullets rips into a nerve gas container. While heaving at the control column, Probe is exposed to the nerve gas which would have killed a normal man but which merely gave him hallucinations. The computer guides him through the hallucinations in time to deal with a third terrorist. Recovering, the computer instructs him to land the Vulcan bomber safely.
