After losing her sister to an overdose, Chief Superintendent Jo Howe is desperate to tackle the world of drugs that consumes the shadow y backstreets of Brighton. Operation Eradicate is her response but not everyone sees it as a positive development.

With connections in the highest levels of government, media and organised crime, Parsons unleashes a brutal counterattack on Howe.

How will she survive being caught in the line of fire?
