During the last two years of her life, Princess Diana embarks on a final rite of passage: a secret love affair with Pakistani heart surgeon Hasnat Khan.

Celebrated and adored by millions, she was the queen of people's hearts, yet the bittersweet story of the last man to truly capture her heart has never been told. Princess Diana (Watts), at one time the most famous woman in the world, inspired a nation with her generosity, compassion and kindness--and in her final years she met the man, Dr Hasnat Kahn (Andrews), who in turn inspired her.

Diana (Naomi Watts) divorces Charles, Prince of Wales, and falls in love with Pakistani Heart Surgeon, Dr. Hasnat Khan (Naveen Andrews). She tours Angola, Australia, Pakistan, New York, Bosnia, Italy Paris, France. She was refused by Khan and began to date Egyptian Dodi Fayed which lasts until their death in a car crash at Pont Alma Tunnel, at Paris, France on 31st Aug 1997.

Diana, Princess of Wales, is formally separated from Charles in 1992. By 1995 they have been living separately for 3 years. Diana is clearly the "People's Princess" and a darling of the masses. She attracts huge crowds at every public appearance. Diana is deeply involved in numerous charity activities and uses her celebrity status to bring attention to issues that she cares about. Diana lives in a huge mansion all by herself, as she does not have custody of her own kids. She maintains a diary. She takes regular acupuncture classes to cure her anxiety.

As she is not yet legally divorced, Diana is called upon by the palace to attend official engagements but is allowed to see her sons Harry (Harry Holland) and William (Laurence Belcher) only once every 5 weeks. Patrick Jephson (Charles Edwards) is her private secretary. Patrick keeps pushing Diana to reconcile with the royal family as she would still have a chance to become Queen one day.

Diana meets Dr Hasnat when her private message therapist's husband has a heart attack & Diana goes to visit him in the hospital. Diana likes Hasnat as he treats her as an ordinary person and not as a princess. Diana offers to help Hasnat by getting donations for the various charitable projects of the hospital. Their acquaintance grows into a friendship & Diana starts inviting him over to her palace for a private dinner. Hasnat is brutally honest with Diana and tells her that she is a bad cook. They share a hearty laugh and order hamburgers from a nearby fast-food chain. Hasnat realizes that Diana is a normal person and enjoys sports and shows on the television just like anyone else. Diana tells Hasnat that she is separated from Charles and hence it is OK if he visits her more often. She had her trouble with the paparazzi from the very beginning who would hound Diana over speculations of a divorce with Charles.

Hasnat is hesitant to start dating Diana fearing that the media attention would distract him from his job. So, Diana disguises herself with a wig to start dating Hasnat. On Nov 20, 1995, a BBC interview with Diana was aired in which she directly accuses Charles of infidelity with Pamela Parker Bowles. Diana also publicly states that she does not aspire to be Queen of England. Diana says that she does not follow the royal rule book and does things by her heart.

Diana is further isolated in her social circle because of this interview. All her friends respond that the interview was a mistake. Her Secretary Patrick resigns on account of it. Patrick says that he worked all this while to reopen doors for her, and now she has shut them permanently.

This drives Diana closer to Hasnat & she sleeps with him.

A year later Diana is engaged with anti-land mining missions in Angola & fights attempts by the palace to suppress the publicity she is trying to generate for this cause. Diana meets victims of land mines who have lost limbs due to the scourge of land mines across the countryside. Diana uses her celebrity status & walks across land mine cleared fields to bring the attention of the world & gather support to stop land-mine production.

Diana goes to extraordinary lengths to avoid the paparazzi and to continue seeing Hasnat. Hasnat tells Diana that an average heart surgery goes on for 8-9 hours and that he needs to be completely focused on his work. Diana accompanies Hasnat in the operating room and sees how Hasnat has the power to save his patients from death. Diana gets her divorce from Charles. Diana's affair with Hasnat goes public. Hasnat breaks up with Diana after she tries to protect Hasnat by rubbishing the story, which ends up making Hasnat a walking joke at his workplace.

Diana goes berserk, but finally manages to get her act together & patch things up with Hasnat. To move things forward she goes alone to Pakistan to meet Hasnat's family. Hasnat's mother is critical of British role in the partition, but eventually seems to accept Diana. Diana travels to Italy to help support the cause of old age homes for the elderly. She meets Prof Christian Barnard, to whom she confides that she loves Hasnat & wants to marry him. She asks for Christian's help to find Hasnat a job outside of England where they can live their life in peace.

Diana travels to NY to auction her gowns to raise money for AIDS research. Hasnat is very upset when he finds that Diana used her influence to get him a job in Boston. They break up only to patch up again. Hasnat's uncle advises him that his mother does not approve of Diana as she is a divorcee & a Christian. Also, he feels that Hasnat cannot be a successful heart surgeon in the media attention his marriage to Diana would bring upon him. Hasnat makes his choice & chooses his profession over Diana. They get separated for the last time as Diana is devastated.

As Diana & her staff deals with the media aftermath of her separation, she receives an invitation from Dodi Fayed (Cas Anvar) to join him on his private yacht. Diana accepts the invitation & this time makes the relationship public from the very beginning. Despite her private life taking on bizarre turns, Diana continues to promote the cause of anti-land mine operations in Bosnia. Her relationship with Dodi attracts tremendous paparazzi attention who follow their every move. Diana is deeply upset. Dodi and Diana are in Paris in Aug 1997. Dodi & Diana are killed in a car crash on 31st Aug, while being chased by paparazzi, in a Parisian tunnel.
