The Nun tells the origin story of the demon Valak. Littered throughout The Conjuring Series, the demonic Nun has proven to be a thorn in the side of those who fight for good and her backstory has remained a mystery, till now.

Throughout this article, I will be discussing the plot of The Nun as well as the film’s ending. There will be heavy spoilers so it may be worth skipping this video for now if you want to go in with fresh eyes.

With that out the way, I’m Deffinition and I ruin the movie so you don’t have to.

Plot Synposis

After the mysterious suicide of a Nun at the Carta Monastery, priest: Father Burke and new practicing Nun, Sister Irene are sent to investigate.

Arriving at the Monastery, the two discover some unorthodox things about the worshippers there that hint at the fact that all is not what it seems. The duo discover that the castle was previously owned by a mysterious man named The Duke that used the castle to open a hole to hell and summon dark forces.

Aware of this, the church intervened and sealed the hole to hell by using a special flak that contained Jesus’ blood. However this Hole was reopened after a bombing in World War Two which is why evil forces began to take over the Castle once more.


As Sister Irene investigates she interacts with Nuns throughout the Monastery. This triggers a vision that instruct the Sister to follow The Virgin Mary in order to find the Blood Of Christ which can reseal the hole. The investigators, with the help of a man named Frenchie go on their quest, however, Irene becomes separated and faces danger at every turn. Valak stalks and attempts to take over her body in order to leave the confines of The Monastery. This is during an attack in which we realise that the other Nuns who were inhabiting the Monastary were infact spirits there to draw in the noon to be nun to become a host for the demon Valak.

Sister Irene manages to spit the blood of Christ into Valaks face which she believes kills The Demon. However, this is a guise and instead Valak transfers into Frenchie. As he is a world traveller this will give the demon free reign over the world. We learn he has Valak inside of him due to the fact that he has an upside down cross embedded on the back of his neck, similar to the one that Valak tried to put on Irene earlier in the film. This is a motif of The Conjuring franchise as Demons often mark or attempt to mark those that they seek to control. We then see footage of an exorcism performed by The Warrens in which they inadvertedly free the demon from Frenchie but in turn put it into the mother from The Conjuring, thus setting up the events that happen in that film.

My Breakdown

A prequel based around a character that appears later in the series was never going to have a scene in which they were defeated but even so, The Nun still managed to surprise me with it’s ending. It beautifully ties into the seriesĀ and highlights just how strong the demon Valak is. It’s a nice twist that doesn’t ruin the films that preceded it as prequels often do and I think the film definitely is worth checking outĀ if you’re a fan of the series.
