From his 'Fake House' stuffed with counterfeit goods, presenter Dominic Littlewood reveals the extent of people using fake identities in the UK.We follow the UK Border agency as they intercept people with fake identities coming into the country, including a woman carrying a fake passport. We go inside the high security National Document Fraud Unit - which has dealt with cases such as the Lockerbie bombing and the shoe bomber Richard Reid, and look at the work of customs and excise as they intercept fake documents used to create fake identities.We show how a man with no qualifications operated as a fake dentist, and meet the victims of his work. In Birmingham, we meet the council officials who catch people faking disability and using blue badge passes to park for free in the city centre. There's a look at the criminal gangs who are faking driving tests by getting experienced drivers to take the test for learners in return for a payoff, putting hundreds of illegal and inexperienced drivers on our roads, and we show a raid by the Driving Standards Agency investigations team and the police where they arrest a suspected driving test impersonator.
