The dates of the exhibit have been set. Bernd Hoffmann is in Lisbon, which he had already visited in 1974, when he met the young artist Hanna Brauer. The exhibit will present paintings by both artists. Bernd is waiting for Hanna, but neither she nor her paintings seem to have arrived in Portugal. And yet he knows that the woman is in Lisbon. He looks for her among his old revolutionary friends, then turns to the police for help. He discovers that Hanna is dead. A natural death? Suicide?
