The New York subway system has:
656 miles of track... 468 stations... 31 thousand turnstiles...
1.64 BILLION fares yearly.
For six of those fares, the trip is going to be one they will never forget.
Six strangers will board a subway. But this subway is unlike the others.
This subway doesn't take you where you want or where you need. It takes you where you fear.
This subway...is DARKBOUND.
