Excitement is running high in the Adams family. Mr Finch, after a long career in secret government work, is to be knighted - which means that Chinese Lady will become a real 'Lady'l What with having to find a new outfit suitable for the occasion, and worrying about whether she'll have to curtsey to the King, the redoubtable matriarch of the Adams family scarcely knows if she's coming or going. Her grandson Paul, meanwhile, working for the Young Socialists, is worried at what his fiery colleague Lucy will say if she learns that he has titled connections. And Sammy, trying to rebuild his clothing business after the War, is horrified at the growing fashion for denim jeans, which even the young ladies of the family seem to be wearing. Should he forsake his bellefs that girls should dress like girls and start stocking these objectionable garments? All differences are resolved, as the great day dawns when the Adams family goes to the Palace for their proudest moment.
