A resident named Marco is confronted by Anna and another neighbor over an air conditioning system he installed in the shared building. They accuse him of causing everyone's electricity bills to skyrocket and installing it primarily for his mother's benefit, not for the community. Anna demands he now pay the entire building's extra electricity costs. When Marco refuses, they give him an ultimatum: pay the bills or remove the AC equipment from the common areas entirely. The episode ends with the accusers united, forcing Marco to face their collective demand.
