At night in Manhattan, New York, twilight envelopes the elites returning home from Wall Street or Broadway, causing their various luxury cars to block the one-way street next to Central Park. Central Park has always been famous for its beautiful scenery. What few people know is that its crime rate is much higher than that of other areas in the United States. Just like the nuclear power plant next to MIT, it accumulates the power to resist the light. What wanders around in the night is no longer the elves during the day, but the silent spirits that died here due to various reasons in the middle of the night. If the night is the source of evil, then everything starts over again here. And our story takes place underground here.
