The police raid the brothel run by the villain, rounding up the illegally trafficked girls - but the villains solicitor produces 'proper papers and valid passports' which he claimed to have been holding for the girls, which show that they are from Bulgaria. As an EU country (as Britain was then) they are released, even though the police know (via their Bulgarian cleaner - who tried to speak to the girls), that they are not Bulgarian (they are from Dagestan). I would expect an opportunity to jail or disbar a rouge lawyer in the act would spark is own criminal investigation, but they just give up and move on.
