Paris after the Second World War. A man no longer remembers. The only clues for his search: an old photo, a death notice. He encounters a small group of emigrants involved in shady dealings. Among them are a bar pianist, a gardener, and a photographer. A Russian dancer appears - and then disappears again. An English jockey crosses his path - and a Greek night wanderer, who is murdered by a chance acquaintance. Who is this seeker? Was he really married to the mannequin Denise, who mysteriously vanished? And what happened at the Swiss border after the war ended?.
