The slightly irksome Dominic Littlewood follows a private investigator working with police and trading standards as he tracks down one of the largest hauls of fake gold and jewellery ever discovered in the UK. And we see the work of the London Assay office as they analyse what the fake jewellery is really made of - with shocking results. We see how the UK Border Agency is stopping international forgers using air cargo to get fake ID into the country and a fake holidaymaker is revealed with her 'crib sheet' of how to respond to immigration officials' questions. Plus, how they tracked down the fake footballer, an illegal immigrant who made a fortune by buying property using fake ID while he played football for local clubs.
