Tony Manero is a Brooklyn paint-store clerk who’d give anything to break out of his dead-end existence. In life, Tony is a peasant; on the disco dance floor, he’s a king. As the soundtrack plays one Bee Gees hit after another, white-suited Tony struts his stuff amidst flashing lights and sweaty, undulating bodies. Tony’s class aspirations are mirrored in his relationship with his dance partner, a secretary eager to move into the glamorous world of Manhattan.

In the slums of the upper West Side of Manhattan, New York, a gang of Polish-American teenagers called the Jets compete with a rival gang of recently immigrated Puerto Ricans, the Sharks, to “own” the neighborhood streets. Tensions are high between the gangs but two kids, one from each rival gang, fall in love leading to tragedy.
