San Francisco serves as the grim backdrop for a disturbing descent into deprivation and murder. The morbidly obese Ethel Janowski is released from an institution into her grandmother’s care, despite the unease of physician Dr. Gerard. At the grandmother’s home, she begins to gorge on food, insisting that staff at the institution had tried to starve her.

To curb the binge, Mrs. Janowski empties the fridge and locks the cupboards, but the pressure only grows. When she threatens to call the doctor, Ethel stabs her to death, then wrenches the cabinet key from her grasp, locks the corpse in a bedroom, and places an order for more groceries.

When the delivery arrives, the delivery boy, Glen Dickie, finds that Ethel cannot pay and she stabs him with a broken bottle as he tries to leave with the groceries.

Ethel’s sister, Rosalie, arrives and announces she will stay for a few days. Ethel ignores calls from the doctor and works to cover the odor from the locked room as Rosalie complains about the stench.

At a bar, Rosalie runs into her ex-boyfriend and pimp, John, and they have sex. That night, the doctor visits again to check why Ethel has missed appointments; Ethel bludgeons him with a candlestick and places his body with the others.

Three days later, Detective McDonough visits to question Ethel, and she offers evasive statements.

That night, Rosalie and John, unable to tolerate the smell any longer, attempt to break down the locked door in the morning. Ethel murders them, using a cleaver.

The detective returns to re-interview her, and she gives contradictory information before he leaves.

Ethel dismembers her victims, stuffs the pieces into sacks, and drives them to a seaside area to dump them into the ocean. But too many witnesses are around, so she brings the bags back home and drags them inside; on the way, she forgets to close her car trunk, and a suspicious neighbor spots a severed hand and calls the police.

In the end, the detective walks in on Ethel eating one of her dead grandmother’s arms.

Criminally Insane Spoiler-Free Summary

Discover the spoiler-free summary of Criminally Insane (1975). Get a concise overview without any spoilers.

In the mist‑laden streets of San Francisco, a city already famous for its stark contrasts, a peculiar unease settles over an unassuming neighborhood. The film opens with the stark walls of an old asylum giving way to cramped, modest apartments, hinting that the line between civilization and madness is thinner than most would admit. The setting feels both ordinary and oppressively claustrophobic, a backdrop that amplifies every whisper of hunger and every flicker of dread.

Ethel Janowski emerges as a force of raw, unfiltered appetite, freshly released from institutional care and thrust back into the world with little more than a lingering reputation and an insatiable hunger. Her massive presence—both physical and emotional—casts a long shadow over those who try to help her, and her struggle to reconcile freedom with the fear of starvation becomes the film’s unsettling heartbeat. The audience is invited to feel the tension between her yearning for sustenance and the world’s instinct to protect her from herself.

Around her, well‑meaning but uneasy figures begin to circle. Dr. Gerard, the physician who once monitored her, returns with a cautious professional curiosity, while Mrs. Janowski, her grandmother, assumes the mantle of caretaker, attempting to enforce a fragile routine. Rosalie, Ethel’s sister, arrives with her own baggage, adding another layer of family dynamics that clash with the central obsession. Their interactions are laced with a nervous humor and an underlying dread, suggesting that every attempt to curb Ethel’s cravings may provoke something far more volatile than a simple protest.

The tone hovers between grim horror and darkly comic suspense, painting a portrait of a woman whose fury is as monumental as her appetite. As the city’s fog rolls in each night, the story teases the audience with the question of how far anyone will go to keep a loved one fed—or, conversely, to keep them from feeding at all. The atmosphere remains taut, promising a descent into chaos that feels inevitable yet remains maddeningly unpredictable.
