Head of the Family

After discovering the Stackpool family's secret, that they're quadruplets with extraordinary abilities, Lance sees an opportunity for personal gain. He forces them to kill his rival Howard and demands $2,000 weekly in exchange for his silence, knowing the family sits on oil and coal riches that make this payment trivial.

Earlier, Lance witnesses the Stackpools dragging a man from his truck, establishing his knowledge of their dark secrets.

The Stackpool quadruplets each possess one exaggerated human trait: Otis has superhuman strength, one sibling has ultra-sharp senses, another is stunningly attractive, and Myron, the head of the family, has exceptional intelligence and psychic powers that allow him to control his siblings.

Lance first notices something unusual about the family when he sees them abducting a man at night.

Myron is a gigantic head perched in a wheelchair who serves as the true leader of the Stackpool family. He wields psychic power over his siblings, commanding them like a puppeteer controls marionettes. His ambition drives the family's dark experiments, as he seeks a normal body to house his superior intellect.

The description notes Myron 'orchestrates their strange, coordinated life' from the very introduction of the family.

Myron grows tired of Lance's constant blackmail and decides to eliminate the threat permanently. By capturing both Lance and Loretta, Myron aims to destroy all evidence linking the outside world to the Stackpool family's secrets and ensure their dark operations remain hidden.

The timeline shows Lance's demands escalating from killing Howard to demanding weekly payments, building Myron's resentment.

To force Lance's compliance, Myron stages a macabre mock trial with Loretta cast in a Joan of Arc scenario, tied to a stake with burning imminent. The grim setup demonstrates how far Myron will go to maintain control, using psychological terror as leverage.

This torture scene directly follows Myron's capture of the couple, escalating the stakes dramatically.

Otis Stackpool, the strong quadruplet, intervenes when he sees Loretta in danger. Despite being controlled by Myron, Otis acts to protect 'the pretty girl' and aborts her execution. He then abducts her from the house and sets it ablaze to destroy all evidence of the family's secrets.

One Stackpool sibling is described as 'stunningly attractive,' creating the emotional connection Otis acts on.

With the Stackpools and Lance dead, Loretta realizes Otis is now the sole surviving heir to the family's immense oil and coal fortune. She marries him and becomes Loretta Stackpool, inheriting control of their wealth and power, trading one dangerous relationship for another.

Loretta's character is established as someone navigating dangerous men throughout the story.

The ending strongly implies Myron survives. Though the house burns and the Stackpools appear defeated, the final moments suggest the mastermind remains alive and is quietly manipulating Otis from the shadows. The chilling implication is that the true villain's influence persists, just out of sight.

Myron's psychic powers and intelligence make him the most dangerous and resourceful character in the story.

Howard, the town thug and Loretta's husband, becomes a target after Lance blackmails the Stackpools to kill him. The Stackpools carry out this execution as part of Lance's demands, removing the violent husband from the picture and clearing the way for Loretta's eventual path to power.

Howard's suspicion about Loretta's affair creates tension early in the film, marking him for elimination.

Myron orders his siblings to perform grotesque human experiments on local idiotic residents. These experiments involve removing brains to create a body suitable for Myron's superior intellect, his attempt to transfer his mind into a normal, functional body and escape his wheelchair-bound existence.

Myron's desire for 'a normal body to house his superior intellect' establishes his scientific ambition.
