Indulging in Nietzsche and Heidegger's amazing whirlpool of existential philosophical thinking, Catherine, a female college student, was determined to find the basis of moral standards in the academic world, but one night on the streets of New York, a strange-looking woman accosted her before crossing the street, then kissed her on the neck in a dark alley, and since then her abstract thinking has become cruel and real. All moral confusion and spiritual redemption depend on her struggling need for plasma. Christopher Walken extradited her like an emissary in the film, making her "night addiction" gradually white-hot. (introduction to the Taiwan version)
