Beginning with a sex scandal that rocked the Catholic Church, Crooks 2 shows us the personal side of some of Williams' most notorious exposés, from the unmasking of one of the world's most infamous drug traffickers to thwarting a criminal's political ambitions, covering the longest gang war in Irish history and disclosing the greed of the nation's bankers with the Anglo Tapes.

For forty years Williams has shone a light where others dare not look, helping victims find their voices.

In Crooks 2 he brings us inside the world of undercover operations, stings and stakeouts in the way that only he can.
