Danny has found a potential new member of the gang, Trevor (played by Lee Ingleby). He's a short con artist, who's very good at what he does, but his marks are not always the greedy; he also targets the elderly and the poor... However, he's looking for his big break and Danny thinks he can mentor Trevor as Mickey has for him. But the team is not as taken with Trevor as Danny, and Danny threatens to walk if they won't give Trevor a chance. They reluctantly trust Danny's instincts and get to work on their next mark.
The target is Anthony Mgabe - a ruthless and corrupt Nigerian billionaire and avid collector of antique currency. He's missing one extremely rare bill - and there are only two in the world. One is held by the American bank, and the other by a private collector. Posing as insurers, Danny and Trevor pay the collector, an elderly lady, Anne, a visit. With an expert grifter creating the forgery, the gang reel Mgabe in. He is so eager to have the currency that he offers Danny and Trevor £500,000. But before they're able to collect the cash, disaster strikes when Trevor loses the bill and the gang is furious about the con falling through. But Trevor can't let it go, and pays Anne another visit. Claiming the bill is damaged, Trevor convinces her to sell and takes it straight to Mgabe to take all the spoils for himself. Has the gang finally been conned themselves? Unfortunately for Trevor, he soon finds out that being greedy never pays and the team is always one step ahead.
