Zaid and his brother are both young Muslim men who live with their mother. Their father is dead; he died a war hero and both boys are very proud of him.
When Zaid starts telling people that The Virgin Mary, a prominent figure, even in The Koran, has been appearing to him on a hillside and speaking with him, Father Jacob investigates and wonders what is actually going on. When he hears that the vision told the boy 'do not worship me, worship my son', Father Jacob is pretty certain that there are dark forces at work as he informs the boy and his family that The Virgin Mary would not say something like that.
Things become more complicated when the boy begins sweating blood and holds his Muslim leader hostage after he sees a vision of his dead father, supposedly in hell, which doesn't make sense to Jacob who tries to reason with the boy and make him see sense about his visions. Meanwhile, Rome gives permission for him to perform an exorcism which greatly weakens the priest and makes it more difficult for him to deal with Michael and perform his work. The consequences could be dire if Jacob cannot get his spiritual and physical strength back.
Although the episode, like the rest, is a good one, it is probably the weakest of the six overall. Still excellent performances from Martin Shaw and Siobhan Finneran as usual.moreless
