'Bécquer desconocido' (Unknown Bécquer) brings us over, from a realistic point of view, to one of the most universal literary figures dismantling some of the habitual topics on him. Across interviews with some experts, the documentary describes to a personality devoided from the romantic myth that has been supposed to him, and confronts some controversial aspects of his life, which passed in a social and politically convulsed period. But at the same time it places him in the literary context to emphasize his relevancy as one of the more innovator authors of his time.
