Spirál (2020) Plot Summary & Ending Explained

The final act erupts inside the precinct, where a rigged contraption hangs Chief Marcus Brazos over the floor like a grotesque trophy. Emerson—the rookie partner who has been feeding Zeke clues all along—reveals himself as the copy‑cat Jigsaw killer. He slides a gun with a single bullet into Zeke’s hand and forces him into a last‑minute test: pull the trigger on a moving target that will free the chief, or turn the gun on Emerson and end the massacre.

Zeke, still haunted by the memory of the department’s brutal past, cannot bring himself to kill his own father. He pulls the trigger on the target, and the mechanism releases Marcus, who drops into a second trap that fires a hidden rifle, killing him instantly. In the chaos, Emerson disappears through a hidden exit, leaving the police force shattered and the chief’s corpse on the floor.
