On the panels of the city, fragments of dialog are posted: a man follows a woman, she enters in a cabin.

On the public cabins of the city, the question “Whoare you?” and a telephone number on which you can leave a message.

A few weeks later. In the street, ringing of a phone box which resounds in the vacuum, without destination.

A passer by approaches, intrigued. The cabin lights of a sharp light. The passer opens the door, enters, takes down the compound, a little constrained. After one moment he hears a voice, somebody says his name, tells his life, an anecdote, is described, his age, date of birth and other things still. Then the message stops, another voice requires: “Whoare you?”, there is a beep, hecan leave a message now… He speaks.

In an official building his voice is mixed with film extracts: a man is in a cabin, he composes a number or receives a call, the conspiracy must remain anonymous.

A little further the street lights again, palpitates, another cabin sounds, another passer by stops. Will he takes the responsability to answer this message which is not intended to him?
