Siren (2017)

That day, a stalwart man from some other country was pinning down an old man in a room on the top floor of a housing complex. Then, the camera starts to reveal their day-to-day so far. This old man had been growing distrustful of the man from other country who lived next door. That very day, the man from other country breaks into the old man's room in the sudden wail of siren. The man holds down the old man, and he storms out of the door, carrying the old man piggyback. Somebody is shouting "fire!" downstairs somewhere. Worried about the old man not coming out of his room, he was just trying to get him out of there. They hurry down the stairs together, looking desperately fierce. Finally and safely, they made it out of the housing complex. They are, however, dumbfounded when they see everyone else outside. In front of them is a perfectly peaceful sight of the residents. After all, there was never a real fire. It was just a fire drill. Up until this drill, it was as if they somehow had a reason to be hostile to each other, but now they have taken this occasion to foster a new relationship.
