Miss Finn was a drama teacher at Weatherfield High. Following the arrest of Kenzie Judd - who was playing the lead role in the school's production of "Mosside Story" - she announced that the play would have to be cancelled. However, fellow pupils and cast members Kayleigh Morton and Sophie Webster persuaded Miss Finn to give Chesney Battersby-Brown an audition for the role. Chesney's audition was successful and the production went ahead.
