The Fast Lady

Murdoch Troon (Stanley Baxter) is a dour Scottish people living and working for a local government authority somewhere in south London. A shy young man, his main excitement comes from cycling. After he's forced off the road by an impatient car driver, he tracks down the owner, only to find that he is Commander Chingford (James Robertson Justice), the domineering and acerbic owner of a sportscar distributorship.
