Ill Gotten Gains follows police officers as they strip criminals of the assets they have bought with cash made from crime. In Episode one we follow police as they seize a Mercedes from a drug dealer who had not paid back the money he made from crime, and we see how elite officers in Derby stop dealers making money in a public park by launching a series of arrests. We also see how high-fashion brands are very popular and selling like hot cakes at the Proceeds of Crime auction.
