Ale (Sandra Escacena) and her boyfriend Jesús (Claudio Portalo) retreat to a secluded treehouse suspended over 20 meters high in a remote forest for a romantic getaway. During the night, Ale is startled awake by their dog barking and witnesses Jesús plummet to his immediate death from the cabin platform. Trapped in isolation and forced to confront the violent forces lurking in the forest, Ale transforms from a targeted victim into a deliberate hunter, executing a calculated plot of retaliation and survival against her attackers.
