Travis Bickle (Robert De Niro) is an ex-Marine lost and adrift in 1970's Manhatta when he finds a job driving a taxi through the hellish streets of the city. One night he encounters a young prostitute (Jodie Foster) and a phoney politician and his life shifts into a new direction. He wants to save the girl and the city from the sewage it wallows in. It moves along to a brillant and final score by the legendary Bernard Herrmann.
