The film explores the fundamental questions that drive Swiss architect Mario Botta's exploration of space. Through Botta's personal testimony and reflections from critics and artists, the documentary investigates the oppositional concepts of the sacred and the profane that are integral to his work. The film also delves into Botta's worldwide projects and his founding of the Accademia di Architettura and the Teatro dell'Architettura, concluding with a look at his exhibition at MAXXI.
