what's the matter with the way i talk

A snobbish phonetics professor agrees to a wager that he can take a flower girl and make her presentable in high society.

When linguistics professor Henry Higgins boasts that he can pass off Cockney flower girl Eliza Doolittle as a princess with only six months' training, Colonel George Pickering takes him up on the bet. Eliza moves into Higgins's home and begins her rigorous training after the professor comes to a financial agreement with her dustman father, Alfred. But the plucky young woman is not the only one undergoing a transformation.

Can Professor Higgins teach a working-class flower girl to speak like a duchess?
