+West Side Story
+
+The award-winning adaptation of the classic romantic tragedy "Romeo
+and Juliet". The feuding families become two warring New York City
+gangs, the white Jets led by Riff and the Latino Sharks, led by
+Bernardo. Their hatred escalates to a point where neither can coexist
+with any form of understanding. But when Riff's best friend (and
+former Jet) Tony and Bernardo's younger sister Maria meet at a
+dance, no one can do anything to stop their love. Maria and Tony
+begin meeting in secret, planning to run away. Then the Sharks and
+Jets plan a rumble under the highway--whoever wins gains control
+of the streets. Maria sends Tony to stop it, hoping it can end the
+violence. It goes terribly wrong, and before the lovers know what's
+happened, tragedy strikes and doesn't stop until the climactic and
+heartbreaking ending.
