Sira, a dance student, has to prepare a year-end course test about Antonio Machado. To do this, she will delve into the life and work of the poet, starring in a cinematographic journey between documentary and fiction. In The Subtle Worlds the biographical documentary investigation and the search for the life experience of Machado’s collection of poems coexist. It is not a trip to the past, it is a search for connection between the poet and our time. (FILMAFFINITY)
