As part of BBC Radio 2's continuing Comedy Showcase series, Richard Wilson stars as frustrated taxi driver Frank Ross, who thinks he's too good for his job.

Frank used to be a Latin teacher and he used to be married. In fact, Frank used to be a lot of things, but now he drives a mini-cab to make ends meet. Adding to Frank's woes his ex-wife, Barbara, is the cab controller at the firm where he works.

Barbara left Frank for local businessman Derek, who owns Town and Country Cars - the mini-cabbing job was a favour to Frank. But it now means he spends more time than ever with Barbara, a situation that pleases no one. And then there's his feckless, layabout son Sean (Ralf Little) who slobs around the house resolutely refusing to get a job.

Frank is forced to act as a budget hearse while trying to arrange a meeting with a Russian oligarch, who wants a tutor for his son. Could this be Frank's escape route out of the vulgar world of mini-cabbing and back into the refined vocation of teaching the classics? More importantly, will Barbara ever get the coffee machine fixed?
