[2] It is based on the novel No una, sino muchas muertes by Peruvian writer Enrique Congrains.

His friend (an owner of an auto-shop and the ringleader of a street gang) invites him to take part in a robbery of a small recycling enterprise run by an arrogant and domineering middle-aged woman named Carmen.

Carmen runs a business operation that consists of sorting out broken glassware in the backyard of her own house for a nearby glass factory.

According to the plan worked out by the ringleader, the gang is supposed to capture an intellectually disabled homeless man from the streets and then try to sell him to Carmen.

When Alejandro knocks on the door, the gate is opened by a beautiful girl named Maruja, the adopted daughter of Carmen.

Barely alive, Alejandro crawls toward a cell where the intellectually disabled workers are kept at night and opens the door for them.

The workers run out and attack the bandits, killing one of them by throwing him on a pile of broken glass, while the other gang member manages to escape.
