The Larkin family lives on a farm in rural England, in the county of Kent. Sidney ("Pop") and his common law wife Florence ("Ma") have six children, eldest daughter Mariette, followed by their only son Montgomery, and other daughters Primrose, twins Zinnia and Petunia, and Victoria. Ma is a housewife while Pop supplements his farm income with various other not entirely legitimate enterprises. Tax collector Cedric ("Charley") visits to audit Pop, but falls in love with Mariette and quits his job to live the rural life. As Ma and Pop raise their other children, Charley attempts to provide for his now wife Mariette. Ma and Pop soon have a seventh child, Oscar, followed around a year later by Charley and Mariette's first baby, John Blenheim.
