We become witnesses to a confession, without silences, with the improbable moments, the absurdities, the disastrous illusions, the portraits of Greeks and foreigners, while protagonists and extras, guilty and innocent, make choices that lead to ruin. But do not rush to judge, condemn or acquit K. Simitis and K. Karamanlis, G. Papandreou with G. Papakonstantinou, A. Samaras-E. Venizelos, L. Papademos and A. Tsipras with G. Varoufakis. "Who Knows?" shakes the complacent consciences, throws the last "bottle into the sea" and fades into nostalgia for the joys, surprises and anxieties of a new world without, possibly, the author's generation.
