2001 film by Rafael Montero

When a worker is found murdered on the construction side, the investigation swiftly turns from things criminal to the political circumstances surrounding the building itself. Widespread corruption and neglect by the builder himself are seen to have brought the situation about. Much of the movie is filmed using hand-held cameras, and the majority of the dialogue is in the difficult-to-understand and very slangy Spanish dialect of Mexico City's bricklayers.

After the death of her abusive husband, Matilde finds her new best friend in Miguel, her young, insecure, and disoriented neighbor.
