Once again we follow Eran Cutliffe of the Crown Prosecution Service, this time dealing with the issue of slavery.
The team are trying to put together evidence that gang-run nail bars are forcing underage Vietnamese girls to work for them with little or no pay. However, as the Modern Slaver Act has only just been past, the new law has yet to be tested. Can the team establish everything to make a workable case?
The Prosecutors is on BBC Two at 21.00.
