The Blackcoat's Daughter

The ending of The Blackcoat’s Daughter reveals a haunting and tragic cycle of possession and despair. Throughout the film, we see two intertwined stories: one follows the schoolgirls Kat and Rose, and the other follows Joan, a woman who appears to be mentally unstable. As the story unfolds, it becomes clear that Joan is actually Kat under a different identity, having escaped from a mental hospital after committing horrific acts.

In the climax, Kat (disguised as Joan) kills Rose and her parents, decapitating them and offering their heads to a cold boiler in a ritual-like act, shouting “Hail Satan!” This act signifies her complete surrender to demonic forces, as she believes doing so will keep her company and escape her loneliness. When she is caught and taken to a hospital, a priest performs an exorcism, and Kat’s desire to cling to her demonic companion is evident when she begs the demon not to leave her. However, the demon eventually abandons her, leaving her utterly alone.

The film culminates with Joan (who is really Kat) wandering outside the abandoned school, sobbing in despair. The last scenes suggest that Kat has somehow continued her vicious cycle — even after death, she appears to find her way back to the school, now in the form of Joan, to seek connection with her demonic friend once again. This cyclical nature leaves viewers questioning whether the demon was real or just a manifestation of Kat’s disturbed mind, and the ending emphasizes her profound loneliness and possible eternity trapped in darkness. The unsettling conclusion hints that some dark, unknowable forces persist, leaving Kat forever lost in her own torment.
