Plot

In the 1960s, Mercurio Arboria founded the Arboria Institute, a New Age research facility dedicated to finding a reconciliation between science and spirituality, allowing humans to move into a new age of "Serenity Through Technology" and perpetual happiness. Now, in 1983, Arboria's work has long since been taken over by his protégé, Dr. Barry Nyle. Outwardly a charming, handsome scientist, Nyle is a psychopath who has been keeping Elena, a young girl, captive deep within the lower levels of the institute. Because there is no sunlight or sense of time in this place, the facility operates in "Day Mode" and "Night Mode." Elena only communicates through telepathy and demonstrates psychic capabilities, which Nyle suppresses using a glowing, prismatic device located somewhere in the bowels of the institute, from where it emanates a deep, droning hum.

In an effort to understand Elena's abilities, Nyle subjects her to daily "therapy" sessions, during which Elena begs to see her father, but Nyle tells her she is very ill, and "not ready" for the world. By night, Elena is kept in her room, where she uses her psychic abilities to surreptitiously watch television shows through a video monitor in the wall. Nyle spends his nights at home with his wife Rosemary, a docile woman who appears to exist in a state of marijuana-induced stupor, yet seems to genuinely care for Nyle despite his lack of tenderness towards her. Nyle takes significant quantities of prescription medication, smiling at his insane reflection in the bathroom mirror.

Attempting to elicit an emotional response from Elena, Nyle speaks about her dead mother, whom he calls "beautiful" and "desirable". He hints that a photo of her might be in Elena's room, which she later discovers under her bed.

That evening, Elena's nurse Margo discovers Nyle's case notes regarding Elena in a hidden recess in the wall, finding strange symbols and images that indicate Nyle's violent sexual obsession with Elena. Fearful of what the notes contain, Margo puts them back. Afterward, Nyle receives a mysterious phone call and rushes back to the Institute where he discovers ash from Margo's cigarette near the case notes. Nyle takes a psychedelic drug to calm himself.

Suspicious of Margo, Nyle informs her that Elena has smuggled contraband into her room. Margo later harasses and verbally abuses Elena, destroying the photo, and Nyle deactivates the suppressor device. Elena kills her by telekinetically causing her brain to burst through her eyes. Nyle, having monitored these events, is intrigued by this blatant display of psychic ability and pleased at Margo's death. He allows Elena to leave her cell and reactivates the prism, causing her to convulse and fall to the floor. Nyle then releases an anaesthetic gas into the facility. As Elena lies unconscious, Nyle electronically summons an entity in a helmeted red environment suit (identified as a "Sentionaut"), who injects a tracking device in Elena's neck before carrying her back to bed and removing all traces of Margo's brutalized corpse.

Nyle goes to see Arboria in another area of the institute. Displaying signs of senility and drug addiction, Arboria does not acknowledge Nyle's psychosis, regarding him as his best protégé. A flashback to 1966 reveals that Elena's mother was Arboria's wife Anna, who was present when Arboria led a young Nyle through a procedure meant to allow him to achieve transcendence. As a part of the procedure, Nyle was submerged in a vat of black liquid and experienced otherworldly, hellish visions. Nyle emerged insane and killed Anna. Unperturbed, Arboria submerged the infant Elena in the black liquid. Back in the "present" of 1983, Nyle murders Arboria by administering a fatal drug overdose, which Elena experiences via telepathic link with her father.
