Derek and Clive Get the Horn (1979)

Very much in love, Neil's wedding plans are sabotaged, beginning when he is abandoned, naked, on a Scottish island. A road trip ensues, with Neil encountering many obstacles as he makes his way to London for what he believes is to be his wedding day. Or is it?

Sgt. Cannon (Tommy Cannon) and PC Ball (Bobby Ball) run the police station in the quiet town of Little Botham. When the station is threatened with closure due to a lack of crime, they decide to invent some crimes to justify their existence. When they try to steal a painting from a local rich businessman (Roy Kinnear), they accidently stumble across a gang of real art thieves who have just stolen £1 million worth of paintings. It is up to the two bungling cops to stop them escaping with their haul.
