'Frágiles humanos' ('Fragile Humans') presents a diverse list of people and situations and reflects upon the perplexity of the rapid passage of human time. In such uncertain times as those we live in, which have so easily revealed our innate fragility and feet of clay, Calabuig's gaze places us before a young Italian guitarist, some old school friends who repeated years together to the soundtrack of a song by Battiato, a German musician painted as if thirty years in the future, the difficulties of a marriage break-up in the seventies and eighties, a mysterious church and the lure of a sentence written on one of its walls, the life of an old bookseller in Berlin who gazes at a brilliant orange moon and a couple of elderly cyclists.
