The Corruptor

With the aid from a New York City policeman, a top immigrant cop tries to stop drug-trafficking and corruption by immigrant Chinese Triads, but things get complicated when the Triads try to bribe the policeman.
Danny is a young cop partnered with Nick, a seasoned but ethically tainted veteran. As the two try to stop a gang war in Chinatown, Danny relies on Nick but grows increasingly uncomfortable with the way Nick gets things done.
