Synopsis: 42nd Street tells the story of a humble, naïve young actress named Peggy Sawyer who has come to audition for a new Broadway musical. Unfortunately, due to her nervousness, Peggy arrives to the audition late and misses her chance to join the chorus. Luckily, Peggy soon catches the eye of the famous director, Julian Marsh, and he gives Peggy her big break.

However, the show’s aging leading lady, Dorothy Brock, quickly grows to dislike Peggy. On opening night, Ms. Brock falls and breaks her ankle. Panic spreads through the company, as the show is doomed for closure, until it is suggested that Peggy take the roll. In only thirty-six hours, Peggy learns twenty-five pages, six songs and ten dance numbers and becomes a star.
