Con artists work every angle in this look at British fraud, from the three-cup trick played on street corners to online scams sophisticated enough to drain a stranger's bank account from another country. The film puts the cost in hard numbers: online fraud alone is estimated to cost Britain roughly £3.5 billion a year, and surveys suggest the scam problem touches something like half the population at some point. Cameras follow London police units working the streets to catch operators running the old cup-and-ball hustle in real time, tourists and shoppers as the marks. Alongside the police, the film turns to 'scam-baiters,' amateurs who deliberately engage online fraudsters, waste their time, and expose their methods, turning the con back on the con artist. Between the street-level grift and the digital fraud, the film maps out how scamming has scaled up without losing its oldest tricks, and why a con as simple as three cups and a ball still works on people every day.
