During a scorching heatwave, a group of residents confronts a man named Marco in the building's common area. They present a joint demand letter, stating that Marco must either cover the increased electric bills caused by his air conditioning system or remove all his equipment and belongings from the shared space. Marco defiantly refuses to pay a single cent. The conflict escalates as the residents insist he must dismantle not just the equipment room but all pipes and brackets, effectively shutting down the AC. Marco accuses them of being insane, questioning how the cooling system can possibly run without the infrastructure. With his refusal to cooperate and their demand for removal, the AC's fate hangs in the balance.
