Bobby (Pacino) is a young heroin addict and occasional pusher who frequents New York's 'Needle Park', home to a number of other addicts and dealers. One day he stumbles across Helen (Kitty Winn), a homeless girl in need of direction after a botched abortion, and the pair begin a relationship. Unfortunately for Helen, for all the intensity of their romance there is only one direction in which Bobby can lead her - down the path to addiction and eventual betrayal.
