Pietro is our protagonist who has recently taken a job as the concierge in a condominium in Milan, late in life. Although defining his character as merely a ‘concierge’ perhaps simplifies his role. He eagerly integrates into the occupants’ colourful lives in the flat: Poppi, (an aptly plosive) teasing and rambunctious lawyer; Paola and her autistic 20-something year old son Fernando. And, of particular interest, the Martini family: Luca, a doctor, his wife Viola and their small child Sara. In his capacity as concierge he has free reign to roam the corridors… and cross thresholds.
