It is summertime in a pedestrian street at the heart of the city. Someone parks his/her car, activates the alarm and leaves. We are never going to see who it is. The alarm of the car keeps going off all night, for no apparent reason. Inside their apartments, the characters of the film are annoyed; they protest and threaten to do something about it. The unsolicited, persistent sound of the alarm will not let the characters rest – because tonight their paths are going to cross.
