Watch 20 Feet Below

Literally just below the surface of modern-day New York City lies a fully functioning alternate world placed among abandoned subway tunnels and other underground infrastructure. Made up of misfits, drug addicts, criminals, down-on-their-luck homeless with mental illnesses, and all manner of other individuals who have chosen to live in an insular underground world invisible to average citizens, this secret society of subway dwellers is the subject of this harrowing feature-length documentary.

The young filmmaker takes her camera on a harrowing journey into an unseen world where surface dwellers are outsiders and those within declare war on the city itself and any who would come to threaten their strange way of life.

20 Feet Below is a 2014 thriller with a runtime of 1 hour and 37 minutes.
