West Side Story is an adaptation of Romeo and Juliet. 
Two warring New York City gangs-the white Jets led by Riff and the Puerto Rican Sharks, led by Bernardo. Their hatred escalates but when Riff’s best friend 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. It goes terribly wrong, and before the lovers know what’s happened, tragedy strikes.
