Summary
At a 1950s California high school, greaser Danny Zuko and prim Australian transfer student Sandy Olsson reunite after a summer romance, but their differing social circles - the leather-jacketed T-Birds and the Pink Ladies - complicate their relationship. Through song, dance, and peer pressure, the two navigate teenage identity, reputation, and what they're willing to change for each other.
