Stuck (2017) online

A New York City subway train stops in the tunnel beneath the city with six complete strangers stuck inside the rear car. The strangers are a cross section of New Yorkers, of different race, culture and age. The emotions of the trapped, frustrated strangers explode, as the subway car becomes a kind of magical, musical, conduit cell. A place where strangers reveal through song more of themselves than any of them ever could have imagined.
