John Devereaux, an SAS Warrant Officer, is seconded to the Australian Secret Intelligence Service (ASIS) to do their bidding. Devereaux is handed a mission that will test him to his very core. The mission, infiltrate into Cambodia and terminate two high-value targets. From the jungles of Cambodia to the streets of Sydney and Bangkok – to the secretive dens of Moscow, and the extravagant french riviera – explosive SAS and ASIS action uncovers a shadowy and powerful organisation and brings us face to face with the Russian mafia. Unkown to Devereaux, the Director-General of ASIS, Magnus Webb, is testing Devereaux for a far more important role – as the head of an off-the-books clandestine cell buried deep inside ASIS and known only as MANTRA-6.- Devereaux’s mission has just begun.
