When British soldier Alex McCloud is injured and blinded in Afghanistan during 2010, he is offered the chance of sight using bionic implants, developed by Professor Goldman of Moorfields Eye Hospital in London, in conjunction with Augmented Reality specialist Major Jennifer Sherlock of the CIA. These implants provide Alex with sight and much, much more, proving to be of great interest to both the MOD and the CIA.

His new life as an intelligence officer based in London presents many challenges and opportunities for adventure and love, but it also brings him to the attention of those to whom his unique abilities pose a threat that must be eliminated.
