Heart of the Mountain Pine is a film that pays tribute to a filmmaker virtually unknown to the audience: Llorenç Llobet-Gràcia. His abundant and widely recognised work as an amateur director, as well as his only professional film, Vida en Sombras (1948), unfold a universe ruled by cinema understood as a life passion. His biography confirms the same idea. Our aim is not to illustrate, comment or give an account of Llorenç Llobet's life and work, but to recapture his spirit: his love for cinema and the consequences of obsession as a life force. Heart of the Mountain Pine is a search, the wandering of a character who, moved by the images he has seen in Llobet's films, discovers the cinematic and personal landscape of the Catalan filmmaker. This quest is just an excuse to build his own universe, with its spaces and its characters.
