Dominic Littlewood reveals how families are being targeted by conmen when their children are on gap year trips abroad. We follow investigators from a leading pharmaceutical company who are hot on the trail of fake medicine dealers. Plus, the terrifying story of the fake and highly dangerous hair straighteners, and how deadly fake chainsaws were sold to unsuspecting members of the public. And the tragic story of how the offer of a job - which turned out to be fake - brought one young family to financial ruin. And we show the scale of the fake electricals industry in China by following the work of a UK investigator.
