The tree in Hancock's garden is threatened with felling to make way for a lamp-post and because it is a danger to passing buses. He is incensed and organises a protest march to Downing Street to try to save it.

It's the centenary of the Borough of East Cheam and Hancock has arranged for the BBC to have exclusive TV rights to the celebratory procession. Unfortunately, the Mayor has sold exclusive rights to ITV and the route of the procession doesn't go past Hancock's house where the BBC have set up. Hancock is forced to take drastic steps and provide his own procession at short notice.
