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 banknotes. He's missing one extremely rare note - and there are only two in the world. One is held by the American bank and the other by a private collector.

But before they're able to collect the cash, disaster strikes when Trevor loses the note and the gang are furious about the con falling through. But Trevor can't let it go and pays Anne another visit. Claiming the note is damaged, Trevor convinces her to sell and takes it straight to Mgabe to take all the spoils for himself. Have the gang finally been conned themselves? Unfortunately for Trevor, he soon finds out that being greedy never pays and the team are always one step ahead.
