Cold, clinical, and deeply unsettling, The Killing of a Sacred Deer cuts into the human psyche with surgical precision. Yorgos Lanthimos crafts a world where morality feels mechanical and punishment feels mythic. Dialogue lands like blunt instruments. Meanwhile, dread seeps in slowly until it suffocates.
Detailed Summary
A Surgeon’s Controlled Life
Steven Murphy, a respected cardiac surgeon, lives a pristine suburban life with his wife Anna and their two children. Precision defines everything around him, from his work to his speech. However, cracks appear when he spends time with a teenage boy named Martin.
Martin’s presence feels odd from the start. Steven offers him gifts and attention that seem disproportionate. Meanwhile, Martin begins to insert himself into Steven’s family life with unsettling ease.
The Strange Bond with Martin
Steven introduces Martin to Anna and the children, which feels like a casual gesture at first. Yet Martin quickly develops an eerie familiarity with everyone. He behaves politely, but something in his tone never quite aligns with normal social cues.
Soon, Martin invites Steven to his home. There, he reveals his lonely life with his widowed mother, subtly hinting at emotional dependence. In addition, his mother’s awkward flirtation with Steven adds another layer of discomfort.
Illness Strikes Without Warning
Steven’s son Bob suddenly loses the ability to walk. Doctors find no physical explanation. Tests come back clean, yet Bob remains paralyzed.
Shortly after, daughter Kim develops the same symptoms. Panic spreads through the family. However, Steven clings to rational explanations, refusing to accept anything beyond medical science.
Martin’s Chilling Revelation
Martin confronts Steven with a horrifying truth. Years earlier, Steven operated on Martin’s father, who died during surgery. Now, Martin claims he has placed a curse on Steven’s family.
He lays out the rules with disturbing calm. Each family member will fall ill in stages: paralysis, refusal to eat, bleeding from the eyes, and eventually death. Consequently, Steven must choose one family member to kill, or all will die.
Desperation and Denial
Steven initially dismisses Martin’s claim. He beats the boy, attempting to force a confession. Yet Martin remains unwavering, almost serene in his certainty.
Meanwhile, the children’s conditions worsen. Kim stops eating and begins crawling across the floor. Bob deteriorates even faster, pleading for his life in heartbreaking ways.
Family Turns on Itself
Fear fractures the family unit. Anna demands answers from Steven. Eventually, he confesses his surgical mistake, though he frames it as unavoidable.
Soon, survival instincts take over. Bob and Kim each try to prove their worth. Kim even attempts to seduce Martin, believing he might reverse the curse. In contrast, Bob begs his father to choose someone else.
Movie Ending
Steven finally accepts that logic cannot solve this nightmare. He devises a grotesque solution to maintain “fairness.” He binds Anna, Bob, and Kim in the living room.
Blindfolded, Steven spins with a rifle, firing randomly. Chaos erupts with each shot. Furniture shatters, screams fill the room, and tension becomes unbearable.
Eventually, one bullet strikes Bob, killing him instantly. Silence follows. As a result, the curse lifts. Anna and Kim recover as if nothing happened.
In the final scene, Steven, Anna, and Kim sit in a diner. Martin enters and locks eyes with them. No words are exchanged. However, the tension lingers, suggesting that consequences never fully disappear.
Are There Post-Credits Scenes?
No, The Killing of a Sacred Deer does not include any post-credits scenes. Once the film ends, it leaves you alone with its moral weight.
Type of Movie

- Nicole Kidman – Anna Murphy

- Raffey Cassidy – Kim Murphy

Film Music and Composer
Yorgos Lanthimos avoids a traditional score. Instead, he uses classical pieces and choral music.
Composers like György Ligeti dominate the soundscape. Sharp strings and eerie vocals amplify tension. Consequently, silence often feels louder than music.
Filming Locations
Production took place primarily in Cincinnati. Real hospitals and suburban homes ground the film in reality.
Those locations contrast sharply with the surreal events. Clean, ordinary settings make the horror feel more invasive.
Awards and Nominations
- Cannes Film Festival: Won Best Screenplay (Yorgos Lanthimos and Efthymis Filippou), nominated for the Palme d’Or.
- British Independent Film Awards: Nominated for Best Director (Yorgos Lanthimos) and Best Supporting Actor (Barry Keoghan).
Behind the Scenes Insights
- Yorgos Lanthimos instructed actors to deliver lines in a flat, emotionless tone
- Colin Farrell gained weight for authenticity, then later transformed again for another role
- Barry Keoghan based Martin’s calm menace on restrained physicality rather than overt aggression
- Scenes were rehearsed extensively to achieve precise timing and rhythm
Inspirations and References
Story draws heavily from the Greek myth of Iphigenia. In that tale, a king must sacrifice his daughter to appease a god.
Lanthimos modernizes this moral dilemma. Instead of gods, guilt and consequence drive the narrative.
Also, the film’s style and atmosphere draw comparisons to the works of Stanley Kubrick, particularly “The Shining.”
Alternate Endings and Deleted Scenes
No confirmed alternate ending exists. However, early drafts explored different family outcomes.
Some deleted scenes expanded Martin’s backstory. Ultimately, the director cut them to preserve ambiguity.
Book Adaptations and Differences
Film is not based on a book. It stands as an original screenplay inspired by mythology.
