Inspired by true events, this is a nocturnal thriller that follows the 2015 kidnapping of Chichita—mother of writer Hernán Casciari—by Daniel Olesnik. Olesnik seeks to settle a blood debt: to avenge a prank played by Hernán and his friend Chiri back in 1987, which drove his own mother to suicide. It is an inescapable, suffocating, and deadly spiral of vengeance that unfolds over the course of a single night.
