Agent Luke Barron is out-of-step with his bosses. The deputy director of the country's State Threats Division fears infiltration by third-world extremists and China. Luke says the real danger is from within - the dispossessed, malcontents and desperate politicians aligning under the banner of freedom. With those words he knows that his career is over. He's in a bad way - his wife has recently died, caught out in the last days of Covid lockdowns. Now it's just him and Jack, his pre-school son. Suspicious cyber traffic has been detected coming from a Wellington City old-folks' home. Luke's handler at the Division assigns him to the investigation. He must go in undercover, as a cleaner. 'One last job for me,' she says. 'Just a few days, at most.' So simple, in and out, job done. Instead, he becomes a hunted man, discovers the truth about his wife's death and uncovers a threat to the nation.
