At the Sand Beach nuclear power plant, head physicist Paul Hanson suspects that the supposedly fail-safe reactor system has a built-in flaw that could trigger off an accidental atomic explosion.  Torn between professional loyalty and the safety of thousands, Hanson realises that the cost of rectifying this lethal defect could mean commercial suicide for the Company.  But what neither Hanson nor his superiors know is that one revenge-obsessed man with access to the reactor’s heart has lunatic designs of his own which – if not discovered in time – will wreak the worst human devastation  the world has seen since Hiroshima.
