This insightful drama follows the life of Arun Kumar (Fahadh Faasil), a young Oncologist working in Dubai. He lives off of plastic money (carrying around a wallet full of credit cards), drives swanky cars and enjoys life to the hilt without worrying about the future. The risk of such a lifestyle comes into focus when his car gets towed away by creditors, and slowly, one by one, his unsustainably lavish lifestyle begins to fall apart like a house of cards in a storm.
The focus is on his relationship with the people around him. There is Savithri Akka (Rohini), his boss in the hospital who, in a sense, spoils him with sisterly affection. Lakshmi (Gauthami Nair), a newly recruited Tamil nurse in his department may be the first girl Arun is seriously smitten by. Lakshmi came to Dubai to fulfill her mother's dream of building a hospital in their village, after her father died due to lack of proper treatment.
Maya (Samvrutha Sunil) is a relative of Savithri, a fashion designer who was based in UK and Paris and now in Dubai. She wants to start her own boutique in Dubai. Maya is engaged to Mr. Deepak,who is in France. Maya is diagnosed with cancer and treated by Savithri. Maya's fiancee Deepak leaves her due to her illness, leaving Maya depressed. While moving Maya's belongings to the ward, Arun notices a diamond necklace.
One day, Arun comes to know through Venu (Sreenivasan), a laborer who is from his town in Kerala, that his mother is not well. But, Arun cannot leave the country due to his creditors. He gets to meet Mr. Narayanan,who also happens to be from his place. Through Narayanan's influence, Arun is granted permission to leave the country.
When he arrives in India, he is tricked into marriage to Narayanan's niece, Rajasree (Anusree). Rajasree is a typical "village" girl who has no clue about city life.
When he comes back he finds out his friend's family has returned and he can no longer stay with him. He then goes searching for a space, but finds that he does not have enough money to pay the advance. He moves to the labor camp with where Venu is staying. Lakshmi eventually comes to know that Arun is married and puts an end to their relationship.
Then finally,he ends up staying with Maya, who was apparently searching for a person to share her spacious flat. Arun and Maya develop a liking for each other. Maya was unaware of the fact that Arun is married. Savithri forces Arun to vacate Maya's flat and bring Rajasree to Dubai. Maya happens to see Arun and Rajasree together in a mall.
This leaves Maya mentally shocked and her illness further aggravates and injecting morphine,a pain reliever,is the only option. Upon Maya's request, to relieve her pain, Arun injects an excess dose of morphine. Arun, to pay off his dues steals Maya's diamond necklace and replaces it with a fake one. Meanwhile Maya admits that she is sorry to have entered into Arun's life and falls asleep.
Rajasree, on finding the diamond necklace, thinks it is her birthday gift from her husband Arun.
Maya develops complications of the overdose and narrowly escapes death. Lakshmi,who was on duty at that time and had injected an initial dose of the pain reliever, gets dismissed from duty. Maya leaves the hospital leaving a gift cover with Savithri to be given to Rajasree by her husband, Arun. When Arun opens the cover the gift eventually turns out to be the fake diamond necklace that he replaced.
Arun drops Lakshmi at the airport, and puts the original diamond necklace into her bag, so that she can fulfill the dream that she and her mother had seen, the hospital. Maya, even though lost all her hair as a result of the treatments, is now seen living a lonely but happy and content life at some remote Himalayan valley remembering Arun's words to live life without worrying about past and future.
The story ends with Arun realizing that Rajasree loved him more than the diamond necklace (the fake one, a fact that Rajasree was unaware of) that he had given her, when she throws it into the ocean to prove her love to him.
