A group of friends unleash a demon while partying on a wild night, and even though they are totally high and wasted, they have to become improvised exorcists to save their lives.
It‘s late night in Buenos Aires. A group of friends, in the midst of a wild, drug-fueled party, are terrified when Julian’s girlfriend suffers a seizure after taking a highly potent hit of acid. Calling her psychiatrist—and father figure—the friends are instructed to take the girl to her house where she begins to act even more strangely. Discovering that she’s also taking psychiatric medication, the unorthodox doctor plans to blast her with aggressive shock treatment in order to contain her escaped demons. Things get worse, and the group decides to take the same acid she did and they begin to see what she’s seeing: ghoulish demonic entities encircle the girl and her home, somehow unleashed by the drug.
