Geoffrey "Geoff" Tipps (Shearsmith), Mike Harris (Pemberton), and Brian Morgan (Gatiss) all work at the local plastics injection-moulding company (In the original radio series, this was a nuclear power plant).
In Series 3 Geoff travels to London to become a stand-up comedian (unsuccessfully) after being sacked by Mike, only to be accused of terrorism and having to return to Royston Vasey as police are searching for him in London.
