This is the first documentary dedicated to Pere Portabella, and it leads us, through the testimony of the filmmaker and his extensive work (which includes films such as Vampir-Cuadecuc, El sopar and Informe general), across decades of Spanish history, from Franco's regime to the present day, including the Transition. He is accompanied on this journey by other figures of the cultural avant-garde, such as Joan Brossa, Carles Santos and Manuel Vázquez Montalbán.

Acteon and Eddie Saeta (Lluis Miñarro) produce Portabella Constellation, premiered in the Venice Classics - Film Documentaries section of the Venice Film Festival.
