"Grease" is a musical about the romance between 1950s teenagers Danny and Sandy, and the events surrounding their respective cliques at Rydell High. Danny belongs to a group of leather-clad "bad boys" called the T-Birds. Sandy, an Australian transfer student and "good girl," falls in with a group of female students called the Pink Ladies. The story features a pep rally, school dance and drive-in movie theater, as well as a climactic school carnival.
Released in 1978, "Grease" stars John Travolta as Danny and Olivia Newton-John as Sandy. At the start of the film, Danny and Sandy have enjoyed a summer romance, but they find it hard to continue their love story in the atmosphere of Rydell High.
Danny tries to maintain his cool image to impress his best friend and fellow T-Bird, Kenickie, and their other friends, Sonny and Doody. Meanwhile, Sandy befriends Frenchy, a girl who considers dropping out of high school to go to cosmetic school. Frenchy tries to indoctrinate her into the Pink Ladies, but the group's antagonistic leader, Rizzo, is convinced that she is "too pure to be Pink."
The film details Danny and Sandy's relationship, from their reconciliation to their split and to their ultimate reunion at the school carnival. A subplot explores Rizzo and Kenickie's tumultuous relationship and her fear of pregnancy.
