The Night Watchman (2011)

From dusk to dawn El velador accompanies Martin, the guardian angel whom, night after night, watches over the extravagant mausoleums of Mexico's most notorious Drug Lords.
In the labyrinth of the narco-cemetery, this film about violence without violence reminds us how, in the turmoil of Mexico's bloodiest conflict since the Revolution, ordinary life persists and quietly defies the dead.
