Steve and Jane travel around England pretending to be market researchers. They con their way into the houses of the rich, to identify things worth stealing on a return visit. Then one day, in a hotel bar, they meet a scruffy old man called Percy. Local gossip has it that Percy is a rich miser with a hoard of money hidden in his tumble-down cottage, so Steve and Jane decide to call on him at home... But there is more to Old Percy than meets the eye. (thetvdb.com)
