Mr Finchley takes a fancy to a horse-drawn caravan that he sees for sale. His new wife does not relish the prospect of a caravan journey so goes to visit her brother while he sets out to explore Kent and go house-hunting. He has various mishaps while learning to handle the horse and the caravan, and encounters an array of scroungers, eccentrics and country characters and sees several unsuitable houses.

Meanwhile other people are showing an unnatural interest in his caravan. It gradually emerges that it contains a secret, and in the ensuing mayhem, Mr Finchley is imprisoned in an empty house from which he is rescued by the enterprise of his wife and of Robert. The house he is rescued from turns out to be on the market and just right for them.
