What Is Psychomania About?
The premise of Psychomania in 262 words, with nothing given away. The full story follows below.
In a brooding English countryside where ancient stone circles cast long shadows over cracked roadways, a restless band of teenagers has forged its own myth. Calling themselves the Living Dead, they stalk the outskirts of their sleepy town, their presence a dark pulse against the ordinary hum of daily life. The film drapes this youthful rebellion in a gothic haze, letting the wind through the standing stones whisper of old rites while the modern world watches, uneasy, from behind curtained windows.
At the heart of the gang is Tom Latham, a charming yet unsettling figure whose fascination with black magic and the occult makes him both magnetic and unnerving. He spends his evenings at the crumbling ruin known as the Seven Witches, a place that feels half graveyard, half altar, where the line between legend and reality blurs. Around him swirl fragments of a strange family worship: his mother’s eerie devotion to a frog‑god and a lingering mystery surrounding his vanished father. Together, they entertain a dangerous bargain—an unholy pact promising immortality to those who embrace death with total belief.
Among the circle, Abby walks a tighter line, torn between affection for Tom and a growing dread of what the pact truly demands. Her perspective provides the film’s emotional counterweight, hinting at a fragile humanity hidden beneath the gang’s macabre swagger. As the teenagers edge closer to a nightmarish promise, the atmosphere tightens, blending the dread of unseen forces with the restless energy of adolescent rebellion, leaving the audience to wonder just how far the desire for eternity can push a soul.

Spoilers ahead
Tom Latham, an amiable psychopath, leads The Living Dead, a violent youth gang that includes his girlfriend Abby. Tom Latham dabbles in black magic and spends much of his time at The Seven Witches, an ancient Surrey ruin formed by a circle of standing stones that evokes Stonehenge.
His mother, Mrs. Latham, and her sinister butler Shadwell conduct séances in their home as they worship the Frog God.
Tom’s father vanished in a mysterious room shortly after Tom’s birth. On his eighteenth birthday, Tom enters that room and encounters the Frog God, an event that sets his life on a dark course.
Following this, Tom commits suicide and, with his mother’s help, returns from the dead. Once undead, he becomes immune to death and displays remarkable strength as he massacres people at a local pub.
Gradually, the biker gang members themselves choose death to join the undead, gathering again at The Seven Witches to plot a campaign of terror against locals. Abby refuses to participate.
Police Chief Inspector Hesseltine, overwhelmed by the wave of biker killings, suspects that someone is looting corpses and even releases a false report that Abby has died.
Hesseltine and his force set a trap for the culprit when he comes to claim Abby. The Living Dead kill the policemen and capture her, but Tom’s mother decides to break her bargain with the Frog God.
The gang pressures Abby to take her own life, but she defies them and shoots Tom, who remains immune. As Tom closes in on Abby, his mother performs a ritual that breaks the pact. She is transformed into a frog, and the undead bikers crumble into stone, becoming new statues at The Seven Witches.
Abby is left alone, surrounded by those who were once her friends.
