The Killing of a Sacred Deer

Steven Murphy, a skilled cardiothoracic surgeon, finishes an open heart surgery, and goes to a diner, where he meets a teenage boy named Martin. Afterward, Steven returns home to his wife, Anna, and their children, teenager Kim and younger son Bob. He later tells Anna that Martin's father died in a car accident ten years earlier, and that he has taken an interest in the boy to help him deal with his grief. Martin comes to the Murphy household for dinner; Kim seems rather taken with him.
