In the divided city of Berlin, invisible, ethereal beings watch over the human population, providing unseen comfort to those in distress. Among these compassionate observers are two angelic entities who wander the city, silently hearing the internal monologues and worries of the people they encounter. They are timeless spirits, unable to directly interact with the physical world but moved by the depth of human experience—by their joy, suffering, and desire for connection. They are particularly drawn to places where thoughts and emotions run high, such as libraries, hospitals, and the bustling streets of the city, bearing witness to the spectrum of human existence.

One of the angels grows increasingly entranced by the vivid life experiences of the humans he observes. His curiosity about the sensory and emotional aspects of corporeal existence deepens to a yearning to become a part of it. As he roams Berlin, his path intertwines with that of a beautiful trapeze artist who struggles with her own sense of isolation and longing. Feeling an unusual and profound connection, he begins to question his celestial existence, contemplating the consequences of trading his immortality and eternal perspective for a mortal life full of love, pain, tactile sensations, and the richness of the mundane. The possibility of such a transformation challenges the very nature of the angel's being and the purpose he has always known.
