Strange Things Happen at Sundown 2003 one on netflix

What happens when normal people find they need to kill, in order to survive? This is the story of such a group of people, suddenly turned into vampires, and carving a path of blood and mayhem throughout New York City. Slowly, they lose their grip on reality, and turn into an army of anti-social, psychopathic misfits; and surely, they turn on each other.
