Amsterdam Vallon (Leonardo DiCaprio) is a young Irish immigrant released from prison.
He returns to the Five Points seeking revenge against his father's killer, William Cutting (Daniel Day-Lewis), a powerful anti-immigrant gang leader. He knows that revenge can only be attained by infiltrating Cutting's inner circle. Amsterdam's journey becomes a fight for personal survival and to find a place for the Irish people in 1860's New York. Spectacular, brilliant, but punishing, with what must be the two bloodiest battle scenes ever committed to celluloid. At the least, the film is a corrective to the accepted notion that urban violence is a 20th-century phenomenon.
