It is the winter of the attack on the Christmas market at the Berlin Memorial Church. A nameless man observes his precarious neighborhood with growing unease. Through conversations and encounters, reflecting on his own biography as well as past life stories, he seeks answers to the question of the nature of humanity, life, and death. He sits in the basement with Dariusz, who was once a surgeon and had a son who drowned in South America. Or with Karsten, a former study colleague, in a bar near the Charité, where he works as a molecular biologist. Or with the elderly Polish architect Dorota, whose intellectual energy is as confusing as it is contagious to him. It hits the nameless guest even harder that he—carrying a piece of homemade cake in his pocket—stands in her emptied apartment during his last visit. Mrs. Do.
