The shows featured the everyday adventures of a group of characters living on Pigeon Street, an area of flats and terraced housing in a British city, also home to several pigeons which appeared in each show but only occasionally featured in the plot. Characters included Clara the long distance lorry driver, her husband Hugo the chef, Mr Baskerville the detective, Mr Jupiter the astronomer, Mr Macadoo the petshop owner, and twins Molly and Polly, who were only distinguishable by the letter M and P on their jumpers.
