Mara spends her nights recording the sounds most people move past without noticing: the last train pulling away, the hum of a corner shop, and footsteps crossing an empty avenue. Julian works overnight at a small radio station, collecting the stories callers share when the rest of the city is asleep. When Mara brings a recording to the station, an unexpected conversation begins. Through exchanged tapes, late-night walks, and stories shared in the dark, they form a connection that challenges the distance both have built between themselves and the rest of the world.
