1/2. Rogue Traders presenter Matt Allwright turns his investigative eye towards con artists who, every year, trick a multitude of unsuspecting victims into handing over millions of pounds. With the aid of a resident psychologist, Allwright identifies and then exploits the scam-mongers' weaknesses to get closer to his prey, paving the way for a roller-coaster pursuit across Europe, Canada and the US.

Laddish presenter Matt Allwright takes the Rogue Traders principle a stage further here. The idea of this series is not just to rumble con artists, but to make them look daft on camera. The programme is filmed in a church and has a self-consciously quirky feel: the kind of approach where the line "we'll mess with their minds" is illustrated by putting a hand-whisk inside a model of a head. There's also a lot of music on the soundtrack to crank up the atmosphere, so we get Bach, the White Stripes and the Raveonettes in too quick succession.
The kind of scams Allwright targets can make big money. Sue Cull in was relieved of several thousand pounds under the impression she was paying taxes on a big Canadian lottery win. If you think she was a bit naive to fall for a stranger asking her to send large cheques, consider this: £40 million was scammed from Brits by Vancouver con artists in the past year, so Sue isn't alone: we seem to be a trusting lot. "I would say there's a certain percentage of your population that unfortunately have become the global suckers," concludes one expert.
The stings that Allwright and friends carry out in turn on the scammers aren't as satisfying as you might hope. Only one of the conmen is lured into making a minor fool of himself, by hunting for some buried treasure. But it's still fun to see villains - the "creme de la crim" as Allwright calls them - get nobbled. (David Butcher)

TV Insider: Suspicion pays dividends
A new breed of international fraudster is exposed in Scambusters (8.00pm BBC1), which takes on conmen in Canada and the USA. "When you get a phone call from someone in Vancouver, you think it's from a healthy, helpful Canadian who goes jogging, but the city has become a big centre for scammers," says Matt Allwright (right). "These are well-organised gangs running clever scams that people won't easily recognise. The only thing you can do is remember there's no such thing as a free lunch," he says. His advice is: If you're going to hand over money, make sure you're absolutely sure you're going to get what you expect in return. Don't rely on the evidence they supply; get evidence yourself. Ask yourself why the person making the offer is doing this - what's in it for them?
