Metro: Last Light - Enter the Metro - Live Action Short Film (Official U.S. Version)

The Moscow Metro. A monumental feat of Soviet engineering, with a dark secondary purpose - to serve as a refuge in the event of an atomic attack. As the Cold War thawed and the threat of nuclear annihilation seemed to fade, this purpose was forgotten -- except by a few, waiting for the signal, ready to open the vaults ... the last refuge for the remnants of mankind.
