In 1994, at the height of his career, Mexican doctor Jacobo Grinberg mysteriously disappeared. The strange circumstances of his disappearance have given rise to multiple hypotheses and theories that have contributed to burying the truth of the case. Considered by many the Einstein of consciousness, Grinberg took the study of psychophysiology beyond the limits of traditional science in order to approach the infinite potential of the human brain and demonstrate the first signs of telepathy.

Director Ida Cuéllar has been investigating the case for seven years and has built a fast-paced metaphysical thriller, revealing unknown evidence that rewrites the account of the last days before his disappearance. Immersing ourselves in the mystery of Dr. Grinberg involves reflecting on the mystery of human existence, and rather than offering answers, we will discover how to ask ourselves better questions.

With a relentless script, an extremely measured sense of staging and a breathtaking dramaturgy, Ida Cuéllar's 'El secreto del doctor Grinberg' is one of the best thrillers of the year on the world stage.

— Carlos Loureda · Fotogramas

It is another good example of the scope that the documentary acquires when it is nourished without reticence by other genres, in this case taking advantage of the subject to skirt that meeting point between science and art.
