Wealthy countryman Mr. Hardcastle arranges for his daughter Kate to meet Charles Marlow, the son of a rich Londoner, hoping the pair will marry. Unfortunately, Marlow is nervous around upper-class women, yet the complete opposite around working-class women. On his first acquaintance with Kate, the latter realises she will have to pretend to be 'common', or Marlow will not woo her. Thus Kate 'stoops to conquer', by posing as a maid, hoping to put Marlow at his ease so he falls for her...but that is only the beginning!
