"Rick Godwin faces danger every single day of his MI5 career. The only problem is that unlike his superiors, he has a conscience and when an operation goes fatally wrong, he walks away. One week later, Rick is back, going undercover in a supposedly violent social justice group. But the group isn't the target. Rick is going after the unthinkable - the enemy is MI5. A rogue intelligence unit has planted two agents in the group - their brief is to smear the group's reputation and incite violence, whatever the cost."
