In a peaceful spot on the French Riviera, a remarkably attractive young actress named Rosemary Hoyt, vacationing with her mother, meets Dick Diver, a charming American therapist. Immediately captivated, she is drawn into the lavish, upper-class lifestyle led by Dick and his spouse, Nicole. However, the festivity unravels when a drunken acquaintance of the Divers commits a crime, triggering Nicole’s mental collapse, and leading Rosemary to witness Dick consoling his troubled wife.
The story then goes back to the events that brought Nicole and Dick together. A Yale graduate and Rhodes scholar, Dick encounters Nicole at a clinic in Zurich where he is studying clinical psychology, and she is undergoing treatment. The affluent Chicago heiress had suffered from her father’s sexual abuse, resulting in her strong aversion towards men. Despite this, the couple falls in love, causing Dick to take on the roles of both Nicole’s husband and therapist. Their life, full of extensive travels and the birth of two children, appears content until Nicole’s condition deteriorates, prompting them to invest in a Swiss clinic. Tensions rise when a former patient accuses Dick of being unfaithful, leading to Nicole crashing their car in a fit of anger.
After hearing about his father’s death, Dick returns to America for the funeral, only to rekindle his romance with Rosemary upon his return. The aftermath sees Dick descending into a destructive path, turning to alcohol, landing in jail, and ultimately losing his position at the clinic. Upon returning to the Riviera, Nicole has an affair and asks for a divorce to marry her lover, Tommy Barban. Recognizing Nicole’s recovery from her mental issues, Dick agrees and subsequently disappears into the American wilderness, never settling down, indicating his ongoing wandering existence.

The narrative now delves into Dick Diver’s backstory. A former Yale student and Rhodes scholar, he studied psychology under Freud in Vienna during the war, before moving to Zurich in 1917. After the war, he returns to Zurich where he reconnects with Franz Gregorovius (known as Dr. Gregory to his American patients), an old friend and classmate. It is unveiled that Dick met Nicole Warren, a patient at the Zurich clinic, before departing for service in France. While in service, Nicole sends him numerous letters showcasing a gradual improvement in her mental health. Her condition, a severe and progressively worsening fear of men, is eventually linked to her father, Mr. Devereux Warren. Following his wife’s death, he and Nicole grew uncomfortably close, evolving their relationship into an incestuous one. Upon this revelation, Mr. Warren is sent back to Chicago by the clinic. Dr. Gregory attributes Nicole’s progress to Dick’s influence.

Despite financial dependency causing hesitation, Dick eventually agrees. After a year and a half at the clinic, Dick and Nicole’s relationship suffers. Matters worsen when Nicole discovers a note accusing Dick of seducing a patient’s daughter. Her mental state deteriorates, culminating in a car accident. In response to these events, Dick takes a break to Berlin. There he learns of a friend’s death, the escape of a Russian prince, and receives news of his father’s passing. He returns to the U.S. for his father’s funeral. Back in Europe, he encounters Rosemary in Rome, reigniting their romantic affair. Meanwhile, Baby urges him to sell the clinic and relocate Nicole to England. Following a drinking binge, Dick gets into a scuffle with a taxi driver, leading to his arrest.
