Andy Bonner, an ex-Special Forces soldier, is struggling in the civilian world after a dangerous life on the edge. Consequently, he loses his boring office job with a bang after a very steamy encounter with his superior. Along with a younger colleague and friend, Paul Brown, he embarks on a new venture, salvaging cargoes from shipwrecks and diving for lobsters off a popular east coast resort.

Two young unattached men, they relish in the abundance of female holiday makers. But the witty camaraderie and carefree life they are enjoying abruptly ends when they find a downed plane and discover evidence of a sinister plot implicating government, cabinet ministers and the PM himself. Brown is picked up and tortured in an attempt to repossess the damming documents. Bonner escapes to London in a last-ditch attempt to expose the plot and save his friend. On the run from the security services he once worked alongside, he has to use every trick in the book and more to survive. On a near impossible quest, Bonner learns that deep deceit is all around him in the form of venal civil servants and greedy corrupt politicians. However, when all seems hopelessly lost, help comes from a most unexpected source… and heads roll.
