Plot Summary

Karin Schluter is driving home to Kearney, Nebraska, the town where she grew up with her younger brother, Mark, who is in his late twenties. Mark has had a car accident and is in the hospital. At the hospital, Mark is disoriented but seems likely to recover. However, he takes a turn for the worse and has to go into surgery. While he is gone, Karin finds a note on his bedstand with a puzzling message in verse. No one at the trauma unit knows anything about the note. After the surgery, Mark appears to recover, but he doesn’t recognize Karin. She looks like his sister, but to him, she seems like an impostor. He begins making up elaborate and improbable scenarios to explain the discrepancy, and the neurologist identifies Mark’s reaction as Capgras syndrome, a delusional condition. Karin shows Mark the note she found on his bedside table, but he doesn’t understand it any more than she does. Mark’s four closest friends visit him at the hospital. Karin considers them a bad influence, but Mark responds better to them than he does to her.

Distressed by Mark’s rejection, Karin calls Mark’s childhood friend, Daniel, with whom she once had a relationship. Something happened when the boys were 14 that shattered their friendship and left them estranged. Karin comes to depend on Daniel for support. He searches out books on neurology, some by Gerald Weber, a neuropsychologist who writes collections of case studies of rare brain injuries and psychological conditions. Karin contacts Dr. Weber, asking him to help Mark.

Mark is moved to a rehab facility, where he and Karin bond with the nurse’s aide, Barbara Gillespie. Mark believes he has completely recovered from the accident, and his continuing disorientation makes him believe everyone around him is lying to him. The only person he trusts is Barbara.

Weber receives Karin’s letter about Mark. He is going through a difficult period in his 30-year marriage and welcomes some time to himself to think about his life and goals. Weber cultivates a friendship with Mark. He also meets Barbara and is captivated by a sense of something broken under her calm exterior.

Weber does a thorough assessment of Mark. He consults with Mark’s neurologist, and they disagree on causes and treatment. Mark’s neurologist takes a purely physical approach to Mark’s condition while Weber focuses on psychological influences. Weber recommends Cognitive Behavioral Therapy to help Mark correct his false interpretations. Afterward, Weber is satisfied with his evaluation and goes back home, where he quickly forgets about Mark. Shortly thereafter, Weber receives a negative review of his latest book. The review accuses him of taking advantage of his subjects. The review triggers the self-doubts that have been growing in Weber for years that he has lost his professional integrity.

Mark is discharged from the hospital, but he fails to recognize his beloved dog or his former home—which was once a source of immense pride to him. His paranoid conspiracy theories convince him his real house and neighborhood have been replaced with nearly perfect imitations. He launches an investigation to find out who left the note on his bedside table at the hospital. He is convinced the writer saved his life and has important information that will explain all the conspiracies.

Frustrated, Karin contacts another former lover, Robert Karsh, a land developer, who is now married to someone else. Karin has noticed that Daniel is bisexual although he refuses to acknowledge it. Robert and Daniel are at odds because Daniel is working to protect the cranes that congregate at the river, and Robert wants to divert water from the river for a development project.

Mark quits cognitive behavioral therapy because he thinks the therapist is trying to brainwash him into accepting the false Karin and all the other changes in his life. As his delusions multiply, Karin writes a desperate letter to Weber begging him to come back.

Weber’s career is in shambles, and he wants to see Barbara again, feeling that she is the only person who can understand what he is going through. Eventually, he returns to see Mark, and this time, he is humbler in his assessment. Realizing that his treatment has actually made Mark worse, he finally researches medical treatments and finds one he thinks will work: the anti-psychotic medication olanzapine. Karin resists the treatment, fearing that Mark, who has tentatively begun to accept the “false” Karin, will no longer love her if he recovers.

Weber retreats, frustrated by their refusal to try the drug therapy. His sense of self continues to crumble. He confesses his infatuation with Barbara to his wife Sylvie, which further strains their marriage.

Daniel comes to visit Mark, and Mark remembers that Daniel had made a pass at him when they were 14 years old. Mark sees now that he overreacted at the time. Karin realizes that she was always a substitute for Daniel’s real love—Mark. Mark’s friends confess to him that they had been at the scene of Mark’s accident. They and Mark had been driving too fast and playing with walkie-talkies when Mark said something about taking evasive action. They found him trapped in his overturned truck, called 911, and retreated, concealing their involvement from everyone. Seeing Mark’s distress and sense of betrayal, Karin finally tells him about the olanzapine treatment. After some internal debate, Mark agrees to try it.

As Mark’s fractured consciousness begins to heal, he becomes depressed and tries to overdose on his medication. Weber seizes an opportunity to come back and see Barbara to resolve his chaotic feelings. Mark remembers seeing something on the road the night of the accident and swerving to avoid it. Barbara eventually confesses that she is the figure he saw on the road. She had been going through her own life crisis and stepped in front of Mark’s truck in order to escape her despair. Mark swerved and saved her life, nearly sacrificing his. Filled with remorse, Barbara became his nursing aide at the clinic. She reveals that she visited Mark at the hospital before his second surgery. While he was still able to remember everything, he wrote the note to her. He is the savior not the saved. This realization gives Mark a restored sense of meaning in his life.

Weber and Barbara engage in a brief affair that enables both of them to solidify their new identities. Barbara confesses that she was formerly a reporter covering the story about the development project on the crane habitat. Burned out on her career and despairing of humanity’s future, she stepped in front of Mark’s truck, intending to die by suicide. Transformed, Weber goes home to Sylvie. Karin goes to work at the crane refuge, finding her own sense of meaning.
