The police arrive outside the room and open fire through the window, to the couple\'s terror. As bullets rain through the room, the band continues playing. Gloria picks up the phone and throws it into a fish tank. As the bullets continue to fly and tear apart the room, Christian and Gloria become calm and walk toward each other, unharmed by the bullets. They embrace and kiss as the room goes dark, recreating the "21st Century Breakdown" cover art. As the song ends, the room lights up again, and they are still uninjured. After the room lights up, there are various shots of destruction in the room, including a shot of some of the writing on the walls. The writing includes an excerpt of the lyrics to "21 Guns", as well as those of the song "See The Light" which is the final song on the album. The video may represent the meaning of the song in the story.']}}]}]
