Watch West Side Story

Two rival gangs have repeated clashes--the Jets, composed of native New Yorkers, and the Sharks who are emigrants from Puerto Rico. The two groups have multiple run-ins with the law and the police warn them against any further fighting. The leader of the Jets, Riff, tries to convince former member Tony to rejoin the gang. Tony shows up at the dance where Riff plans to challenge the Shark leader, Bernardo, to a special fight. However at the party Tony meets Maria, Bernardo's sister, and the two quickly fall in love.

The two lovers meet up again later and talk of their plans for the future and marriage, but Maria realizes they can never be together while the two gangs are fighting. Maria convinces Tony he must stop the planned fight and he races off to try. The fight has already turned ugly though with several members bringing knives and weapons.
