Tony Manero (John Travolta John Travolta) is a 19-year-old young man in Brooklyn, New York, who works in a hardware store during the day and looks like an ordinary teenager. On Saturday night, however, Tony was the shining "dance king" of the local disco. Annette is Tony's dance partner, and the two had planned to take part in the dance competition to be held in the ballroom. However, when Tony met Stephanie Mangano (Karen Lynn Goni Karen Lynn Gorney), she was moved by her dancing skills. Tony's courtship to Stephanie is rejected, but Stephanie agrees to be Tony's dance partner and take part in the competition with him. The two of them practice hard every day. During the competition, the two men gave a wonderful performance and won the first place. However, Tony believes that a pair of dancers are better because they are Spaniards and can only win the second prize. So Tony gave them the first place. At the end of the game, Tony courted Stephanie again. Ben.
