Mr and Mrs Twit are just about as nasty and revolting as two people can get. The only thing that brings the two of them pleasure is playing pranks on one another. But when a new family called the Lovelies move in next door, with their lively 10-year-old twins, they teach The Twits to stop being so mean and horrible and they all live happily ever after - Ha! Not really. The Twits HATE the Lovelies. But how far will The Twits go to rid themselves of their horribly nice new neighbours? And what happens when these new neighbours, who are armed with utter loveliness, start to fight back?
