Takes a lighthearted look at the problem of colour through the eyes of a white couple, Eddie and Joan Booth, and a black couple, Bill and Barbie Reynolds, who move in next door. This series helps to take some of the heat out of race relations by showing the funny side of everyday conflict.

Then Jacko, the confirmed bachelor, announces that not only is he in love but he's actually getting married! Eddie tries to trace his family tree and discovers that he may have royal blood in his veins while Joan and Barbie decide to get Saturday jobs. This leaves Eddie and Bill holding the babies and threatening their regular visits to football matches, a couple of nannies are brought in to rescue them but only ends up with Eddie and Bill both being penalised!
