Grease is a musical set in 1959 at Rydell High School, following the Pink Ladies and T-Birds gangs. The main character Sandy joins the Pink Ladies and tells them about meeting Danny, the leader of the T-Birds, over summer. When school starts, Danny and Sandy are surprised to find they both attend Rydell. Frenchy is an over-the-top member of the Pink Ladies who is friendly and supportive, especially comforting Sandy when Danny treats her differently than over summer. Grease explores themes of love, friendship, and teenage rebellion through songs and scenes requiring strong acting, singing, dancing, and character portrayal skills from the cast.
