Plot synopsis: In a Barcelona suffocated by the housing crisis and evictions, an eccentric serial killer executes wealthy real estate speculators using heavy metal pétanque balls. His targets are ruthless property owners who profit from the silent tragedy of housing displacement and eviction. Dressed like a vintage pétanque player, the vigilante is driven by the social impact of gentrification. Casting himself as a housing Robin Hood, he justifies his crimes as acts committed for the common good. As two detectives navigate the investigation, public opinion splits between viewing the murderer as a heroic housing vigilante or a psychopath.
