On the mean streets of New York City, two gangs are in a long-lasting duel. The Sharks, a Puerto Rican gang, grapple with the difficulties of assimilating into American society. The Jets, the "American" gang, want to resist newcomers entering their territory. In the midst of this rivalry, a Jet, Tony, falls in love with a beautiful Sharks' girl, Maria. Based on Shakespeare's Romeo and Juliet this is a story of Star crossed lovers, Tragedy and Gang feuds.
