Her days are an endless cycle of cleaning up after her abrasive, cab-driving husband Antonio, who openly despises her cooking and openly pines for his former German lover, Ingrid. Gloria’s existence is further complicated by her
dysfunctional family: a teenage son who moonlights as a drug dealer and forger, another son who is a compulsive runaway and thief living with an older homosexual dentist, and a vulgar mother-in-law obsessed with a pet lizard. Her only solace comes from sniffing cleaning chemicals just to escape the crushing monotony of her dreary domestic reality.Desperate for affection and basic human dignity, Gloria finds brief, bittersweet moments of connection with her upstairs neighbor Cristal, a good-natured sex worker who offers her a sympathetic ear and temporary relief from her marital misery.

Instead of panicking, a strange, chilling sense of calm washes over her. She quickly cleans up the blood and hides the weapon. Police investigators descend upon
the neighborhood to question the residents, but despite their thorough inquiries, they fail to pin the murder on the grieving, unassuming housewife.With Antonio gone, the household descends into a profound, eerie silence. The runaway son returns, and the family gathers on the rooftop terrace to survey the sprawling city skyline.
