The main characters are guardian angels—benevolent, invisible beings in trench coats—who listen to the thoughts of mortals and attempt to comfort them. One of them, Damiel (Bruno Ganz), wishes to become human after he falls in love with the beautiful trapeze artist Marion (Solveig Dommartin). Peter Falk, played by himself, helps him during his transformation, by introducing him to life’s little pleasures.

The film is narrated from the perspective of the angels, who see the world in black and white. Only when Damiel becomes human does the world of color reveal itself to him. He leaves behind his old friend Cassiel (Otto Sander), who continues to be accompanied by Homer (Curt Bois), the “storyteller of humanity.”
