The con artists set their their sites on Rhona Christie, a Member of Parliament who is not only ruthless in her business dealings but is also lining her pockets. Her crooked deal is to buy properties with listed buildings at reduced prices and then through her position in government have them de-listed, resulting in a huge rise in value and a substantial profit following a quick re-sale. She's very discreet however and working through intermediaries, keeps her own hands clean; she is, for all appearances, the hard working MP with only the people's interest at heart. With Arthur posing as a local real-estate mogul and young Sean as the inside man working as her unpaid PA, they set about convincing her to invest in a major re-development project. Not satisfied with just taking her money however, they also decide to make sure they ruin her reputation as well.
