Steve and Jane are a couple of thieves who travel the country pretending to be market researchers for Silvertone metal polish whilst they find suitable homes to burgle. In a hotel bar they meet the eccentric old Percy, who, despite his tatty appearance, is rumoured to have a hidden fortune. The couple decide to break into his house but Percy has caught an earlier bus home and surprises them. He will cause them more trouble than they could have imagined.
