When a priest is jailed for the murder of a nun on whom he was performing an exorcism, an investigative journalist strives to determine whether he in fact murdered a mentally ill person, or if he lost the battle with a demonic presence.
In a godforsaken landscape, filmed in transcendental black and white, as if fallen out of time, young Ada lives alone with her ill mother. Her rather lonely existence is characterized by hard work and poverty and as her mother's condition worsens there doesn't seem to be a way out anymore. Ecce homo is a parable about being human, rich in religious symbolism, which dreamily and at the same time sombrely poses existential questions without volunteering answers.
