In English class I saw a part of the film Moulin Rouge and this is a summary of this part.

A young British writer, Christian moves to Paris. he encounters a musical troupe that is attempting to present a new play for the owner of the cabaret, the Moulin Rouge. Christian's writing helps to finalize the show and the troupe take Christian to the cabaret to present the work itself to its star courtesan, Satine in private to win her favour. However, the same night, Zidler has arranged for Satine to spend the night with the wealthy Duke who is looking to buy the cabaret. Through for bad communication, Satine mistakes Christian for the Duke, and the two depart to her private chambers. She begins to seduce him despite his insistence he is only there to present his script, but the two slowly realize they have fallen in love with each other. The Duke returns, and discovers Christian and Satine in a compromising position. Satine quickly states that Christian is only there to present a play. With the help of the troupe, Satine, and Zidler, Christian quickly improvises a new plot to "Spectacular! Spectacular!" as a thinly-covered veil of their current situation, with an evil maharajah attempting to woo the love of an Indian courtesan who is actually in love with a poor sitar player. The Duke, unable to see through the show's meaning, agrees to finance the show, but only if he is allowed to continue to see Satine. Unfortunately for the Duke, Satine and Christian continuously make up excuses as to why he can't see her.
