Grease the film was released in 1978 although it is based on a 1972 musical. John Travoltta and Olivia Newton-Jhon delighted a whole generation of teenagers and their children and their children. The love story between social classes. Zuko is the leader of the Thunder Birds (T-birds) and Sandy first a good girl, who later will be part of the Pinks Ladies (the girl band). The two have met on vacation, but when they return to daily life they coincide again. Zuko has to maintain his role as tough guy before others and Sandy does not understand anything. There are wonderful songs until they find a way to be together ... If you haven't seen it, you have to see it. A little love and social criticism of the time.
