A "brief encounter" on the Athenian Underground brings together two people, Koula and Dimitris, from entirely different backgrounds and ages. For a few weeks they manage to break loose from their respective shackles and meet in a kind of no man's land of passionate discovery. The couple's emotional fluctuations are charted with remarkable precision and subtlety, in a low-key tone that fully captures the muted drama of their meeting and parting.
