Diamond Necklace

Dr. Arun Kumar is a young oncologist based in Dubai, living a life of credit cards and luxury. His carefree attitude masks the growing risk of debt as his extravagant expenses threaten his finances. The threat materializes when creditors threaten to tow his car, revealing the fragility of his lifestyle.

Dr. Savithri Akka, his boss, showers him with sisterly affection at the hospital. Lakshmi, a newly recruited Tamil nurse, catches Arun's eye and he is instantly smitten. They begin a secret romance, navigating their growing feelings in the shadows.

Maya, Savithri's relative and a fashion designer, is diagnosed with cancer and treated by Savithri. While moving Maya's belongings in the ward, Arun notices a diamond necklace worth ₹70 lakhs, signaling a tempting fortune nearby. The necklace becomes a symbol of the moral stakes to come.

Venu informs Arun that his mother is unwell, but Arun cannot leave Dubai due to his mounting debt. Through Narayana Menon, Arun is granted permission to travel home briefly. The arrangement sets the stage for a drastic turn in his life.

Arriving in India, Arun is tricked into marrying Narayanan's niece, Rajasree, a village girl with little exposure to city life. The union is arranged under pressure rather than love, binding Arun to a marriage he did not intend.

Back in Dubai, Arun discovers he cannot stay with his friend's family and cannot afford the housing advance. He ends up moving to a labor camp where Venu is staying, facing a precarious new living situation. The debt and obligations tighten their grip on him.

Lakshmi discovers that Arun is married and ends their relationship, leaving him to face the consequences of his double life. The breakup pushes Arun further toward Maya as a source of companionship and escape.

Arun begins staying with Maya in her spacious flat, and the two grow closer as their bond deepens. Maya remains unaware of Arun's marriage, creating a tense undercurrent beneath their growing affection.

Savithri pressures Arun to vacate Maya's flat and bring his wife, Rajasree, to Dubai. Arun relocates with his wife and resumes a messy, dual life under one roof, fueling the deception that defines his choices.

Arun and Maya meet on Maya's last day in her flat and have sex, unaware of the full marital complications. A few days later, Maya sees Arun with Rajasree in a mall, triggering shock and emotional pain that threatens her health further.

In desperation, Maya asks for relief from her pain, and Arun administers an excessive morphine dose that endangers her life. To pay his debts, he steals Maya's diamond necklace and replaces it with a fake, planning to return it once his loan is settled.

Venu intervenes, speaking to the bank manager and arranging a repayment plan that covers the first installment. Lakshmi, who had administered the initial pain relief, is dismissed from duty due to the incident. The debt and consequences ripple through the hospital staff.

Maya leaves the hospital with a gift envelope for Rajasree, but Arun discovers that the gift is the fake necklace he had replaced earlier. The revelation brings the truth of his deception into sharp relief and heightens the emotional stakes for all involved.

Arun drops Lakshmi at the airport and places the original diamond necklace into her bag, hoping she can fulfill the dream of building a hospital with her mother. The act is meant to be a final, morally ambiguous gesture amid his spiraling debts.

Maya is shown living a lonely but content life in a remote Himalayan valley, remembering Arun's words to live life without worrying about past and future. Arun finally realizes that Rajasree loved him more than the fake necklace, and the film ends with him embracing her in a quiet, reconciled moment.
