Detective Inspector Michael Ballard and his partner Detective Senior Sergeant John Henderson back in action dealing with 'the bad guys'. This time they are fighting terrorists and the action includes seeing them hanging off the Eureka Tower; being holed up in a utilities cupboard while the entire sitting of Parliament is held to ransom in Spring Street; and being taken hostage by a crazed Russian ex Spetsnaz. Amidst all the action their personal lives go on: will Michael and his newly wedded bride Natalie ever get to go on their honeymoon? And why is the usual grumpy John looking so happy these days?
