She stoops to Conquer is a comedy by the Irish author Oliver Goldsmith. The play was initially titled as Mistakes of a Night and the events in the play, indeed, happen duri…ng the time frame of one night..
Mr.Hardcastle, a rich countryman plans to marry his daughter Kate to the son of his old friend, Sir Charles Marlow. Hardcastle's second wife is determined in marrying her spoiled son, Tony Lumpkin to her niece, Constance Neville in order to keep her fortune, a casket of jewels within the family. But Miss Neville has plans to marry Hastings, a friend of young Marlow..
While Hardcastle's family is eagerly awaiting the arrival of Marlow and his friend, Hastings, the friends stop at the village Inn to inquire their way. Tony Lumpkin, who is present there, realizes their identity and plays a joke by telling them that they are far away from their destination and asks them to stay at an inn, recommending Hardcastle house as the best Inn around there. Thus the friends arrive there and treat Mr.Hardcastle as mere Inn keeper. This enrages Mr.Hardcastle and is convinced that Marlow is not suitable for his daughter..
On the other hand, Young Marlow who is nervous in the presence of ladies of his own social status, yet quite the quite opposite with lower-class women doesn't look properly at Kate on their first meeting. Kate realizes this and stoops to conquer him, by posing as bar maid and putting Marlow at his ease so that he falls for her in the process..
However, he changes his mind when he realizes the truth behind Marlow's behaviour. The play concludes with Mr.Hardcastle realizing the truth behind Marlow's behaviour and changing his mind; Kate succeeding in her plan and getting engaged to Marlow; Tony Lumpkin discovering he is of age and receives his entitled money, which his mother hides from him. He refuses to marry Ms.Neville, who then gets her entitled jewels and gets engaged to Mr.Hastings. So all is well that ends well. ( Full Answer )
