Three former Special Forces operatives have built quiet lives operating a commuter airline—anchored by family, a little romance and the hope that old battles would never find them again. But the squad is forced back into a world of deception and ruthless operations. Old scars are reopened and old skills learned in the fire of close combat are called on when an Interpol field operations unit uncovers a multilayered criminal conspiracy stretching from Perth to the capitals of the East and Europe. A mask operation reveals deep ties of brotherhood that force the old Special Forces team to confront a ruthless enemy who operates in the dark.
