The Killing of a Sacred Deer

Steven Murphy is a successful cardiovascular surgeon living in an affluent suburb with his wife Anna, an ophthalmologist, and their two children — teenage daughter Kim and younger son Bob. Their family life has a precise, controlled quality; the warmth in it is slightly performed. Years earlier, a patient died on Steven's operating table. He has absorbed the loss as an unavoidable professional risk, publicly, but the guilt has shaped him in ways he won't acknowledge.

He has been quietly meeting Martin, the dead man's teenage son, in diners — giving him expensive gifts, positioning himself as a mentor, performing atonement at a careful remove. He eventually brings Martin home. The boy is polite and intensely observant; Kim develops a tentative adolescent interest in him. When the Murphys visit Martin's home in turn, his lonely mother attempts to seduce Steven. He recoils and withdraws from the relationship. Martin's affect shifts. He drops the measured politeness and begins speaking in a flat, declarative register stripped of all warmth.

Shortly after, Bob wakes unable to move his legs. Tests reveal nothing. Martin comes to the hospital and delivers his terms in the same calm, expressionless voice: because Steven took a life unjustly — through negligence, arrogance, or pride — a balance must be restored. Steven must choose one family member and kill them. If he refuses, each family member will move through three stages in sequence: paralysis of the legs, refusal to eat, bleeding from the eyes, then death. All of them. Steven treats this as a psychiatric problem and has Martin removed. Bob's paralysis persists and he stops eating. Kim collapses at school and loses the use of her legs. The symptoms cannot be explained or treated by any medical means Steven commands. The anesthesiologist present during the original surgery confirms what Steven will not: there was drinking before the operation. The negligence was real. Martin's metaphysical reckoning is rooted in actual guilt. Steven beats Martin in a parking garage, attempting to force a cure through violence. Martin simply repeats the terms.

The family begins to turn on itself. Bob tries to purchase his survival by performing closeness to his father, promising to be more like Steven. Kim calls Martin and declares she loves him, hoping romantic alignment might spare her; her paralysis briefly lifts when Martin seems to respond, then returns when the call ends. Anna, clinical and unsentimental, tells Steven the mathematically optimal solution is to sacrifice one of the children rather than either spouse, since a child can theoretically be replaced and a partner cannot. Bob's eyes begin to bleed — the final stage before death.
