Reclusive millionaire philanthropist Jason Kincaid Oliver Reed survived a hunt gone wrong when a massive taipan serpent killed his brother in Micronesia. The same venom that struck his brother also pierced Kincaid, yet somehow spared him—the venom is suggested to have mutated the brain cells responsible for extrasensory perception, forging a disturbing telepathic link between man and creature. Haunted by visions of the snake’s continued killings, Kincaid decides to act, paying for a poacher to capture the snake and deliver it to his secluded mansion outside San Diego. To help sever the unwelcome psychic tether, he hires Dr. Tom Brasilian Peter Fonda, a psychiatrist and ESP researcher, and in return underwrites Brasilian’s ongoing investigations. The arrangement is simple in theory: find a cure for the bond, and the benefactor’s wealth becomes fuel for science.
Yet the plot quickly thickens as a Satanic cult learns of the serpent’s existence and desires to wield its power for worship. They see the snake as the demon guardian of the underworld and set their sights on possessing it. To accomplish this, they enlist ex-CIA agent Warren Crowley Al Waxman to steal the creature. Crowley bribes a sailor aboard the transport ship to assist in the heist, but the plan unravels when the mole is bitten and slain while attempting to peek inside the container. The cult’s ambition collides with the kaleidoscope of loyalties around the snake, and the threat escalates from a scientific curiosity to a mortal danger with echoes of the occult.
Kincaid’s family ties introduce Suzanne Kincaid Kerrie Keane, his niece, who is convinced that the psychic link is a delusion born from trauma rather than a supernatural bond. She becomes entangled in the dangerous drama when she secretly tries to kill the snake by raising the temperature of its containment to a lethal 150 degrees. The intruders’ plan triggers a brutal cascade: Crowley and his minder Deacon Tyrone Angus MacInnes break into Brasilian’s lab, and Tyrone, realizing the serpent is overheated, opens the container. The snake strikes with deadly precision, killing Tyrone and the lab director, and then fleeing into the night. Brasilian and Suzanne are summoned to the scene by police, while Kincaid, sensing the danger, braces for what comes next.
Brasilian, ever the pragmatist, concludes that the serpent must seek a temperate climate and directs a search of a nearby greenhouse. The creature breaches the space and launches a vicious attack, forcing Brasilian to fend it off with a fire extinguisher. Police arrive, but Kincaid manages to sway them from charging him with illicitly importing such a lethal animal, convincing them of the danger the snake represents. The serpent does not stay contained for long; it launches a savage assault on a nearby sorority house, slaughtering its occupants as Kincaid witnesses the carnage through his terrifying mental link.
With the cult pressing its bid to recover the creature, Crowley grows increasingly desperate and bribes the location of Kincaid’s residence, hoping the snake will eventually come to him. Brasilian, meanwhile, devises a plan to use Kincaid’s unique brain-pattern signatures to track the animal. A brain-monitoring device is hooked up to Kincaid, and the psychic bond intensifies into a telepathic episode: Kincaid sees the snake reach their house, and in a flood of cryptic sensations he manages to scream out a few last words before the connection collapses. Suzanne realizes that the vision was pointing to their own home, and she and Brasilian sprint to intercept the threat.
When Kincaid arrives at the house, the carnage is already underway. The snake has claimed a groundskeeper, and the grounds around the residence become a theater of escalating visions for the doomed man as he stumbles through the landscape in search of the creature. He draws a knife and fights back, but the psychic energy crackles with explosive ferocity, and the struggle ends with Kincaid fatally overmatched. Brasilian and Suzanne rush in as the last barrier collapses; Brasilian seizes Kincaid’s gun and fires the weapon, wounding—and ultimately killing—the serpent. The snake’s remains burn in the yard, lying side by side with Kincaid as night falls on the house that could not protect him from the monstrous bond he forged with the creature. The ordeal closes on a somber note: science and motive collide with fanatic worship and an unsparing fate, leaving behind a cautionary tale about curiosity, power, and the costs of a connection that should never have existed.
