Documenting his investigation of the government
Project MKUltra, James Hirsch takes
dimethyltryptamine-19 (DMT-19), a drug used in the experiments, while filmed by a friend. Bizarre music and voices are broadcast from a nearby radio. A shadowy figure comes and leaves James with all-black eyes and a disfigured face. Anne, a reporter who attended college with James, is concerned about his disappearance. James's friend also mysteriously disappeared a few days after the police questioned him. Anne investigates James's house and discovers a
betamax cassette containing footage of the MKUltra experiments as well as a book of notes about the project. She consults a local expert, who tells her the bizarre radio broadcast is a
phantom radio station that can only be picked up in the desert at night. Anne drives out into the desert after dark to pick up the broadcast, but flees when a monstrous form appears from the darkness. A clue in James's notes leads Anne to counter-culture writer Thomas Blackburn, infamous for his drug use and unpredictable behavior. After being rebuffed over the phone (over her mentioning Project MKUltra), Anne travels to Blackburn's home and lies to gain his confidence. Blackburn sees through her ruse and tricks her into taking DMT-19. Anne is angry about the deception, and Blackburn's friend Callie begins exhibiting the same behaviors and disfigurement as James. Investigating the bizarre music played by the phantom station, Anne is attacked by a strange entity. Anne and Blackburn awaken to find Callie missing. They head to Callie's house, where Anne is nearly captured by Callie, now under the entity's control. They realize that DMT-19 works as a "radio antenna" that causes the consumers to tune into otherworldly entities' signals and get their bodies taken over. The government received instructions to make DMT-19 from the otherworldly entities and made the drug, unaware of the full consequences. In addition to the base chemical compound, scientists were adding harvested material from the
pineal gland of a female corpse, dubbed the "Primary Source", who returned to life during an experiment and attacked a doctor. Blackburn reveals that he lied about giving her DMT-19. Realizing the entity will pursue her regardless, Anne resolves to end the broadcast. Realizing the signal likely comes from an MKUltra laboratory, the two travel into the desert and discover the laboratory in an abandoned
fallout shelter. Inside, they discover a room full of radio equipment and a large tank containing a pale figure with black eyes (implied to be the "Primary Source"). The radio equipment comes to life and broadcasts the
numbers station. As Anne is chased by a grotesque figure, Blackburn begins to bleed from the eyes and convulse. To avoid being taken over, he shoots himself in the head. In a frenzy, Anne pours the gasoline into the tank and set it on fire. The resulting explosion knocks her unconscious. When she comes to, she finds the clothing James wore before his disappearance lying in the hallway, implying that the creature chasing her was "wearing" James. Anne is taken into police custody and visited by a co-worker. She and Anne discuss the tape that Anne discovered. Eventually Ann realizes that DMT-19's effects can be passed along by human touch, which explains why she sees the creatures without having taken it. To her horror Ann discovers the entities have taken over her coworker (whose hand she had held earlier). Recovered footage on the tape reveals another Project MKUltra test subject: a college-aged Blackburn. ==Cast==
