How can an ordinary man have a breathtaking, goose flesh igniting, awe inspiring love story of all things to tell?

What follows is a journey filled with laughter, tears, joy, pain, music, dance and a lot of love. A journey that makes us believe that there is an extraordinary love story in every ordinary jodi (couple).—Official Source

Shy, introverted, and kind of heart Surinder "Suri" Sahni (Shahrukh Khan) is an office worker for Punjab Power. Suri is invited to the wedding of his former professor's (MK Raina) daughter Tania. Suri used to be his favorite student. Tania is having a love marriage. Tania had heard from Suri from her father as he would always encourage her to be more like Surinder and even wanted them to get married.

Suri quietly falls in love with the beautiful and vivacious Tania "Taani" Gupta (Anushka Sharma), whom he first sees during the preparations for her wedding. Taani's father suffers a heart attack when the entire wedding party learns that her fiance and his family were killed in a traffic accident. Fearing that Taani will be alone in the world, the professor asks Suri to marry her. Suri concedes and Taani tearfully agrees only to please her father.

After a hasty wedding, Suri takes Taani to his ancestral home in Amritsar. While his good nature leads Suri to treat her with exceptional care and patience, he is too frightened to profess his love for her. However, Taani tells him that while she will try to be a good wife, she can never love him due to having no love left within her. Suri sleeps in the upstairs room of the house and Taani in the downstairs room. The two rarely talk. Suri gets up every morning, makes his own breakfast and goes to work and Taani only comes out of her room after he has left for work.

Khanna (Rajesh Jais) and DK (Anuj Tikku) are Suri's colleagues at work. Balwinder "Bobby" Khosla is Suri's only friend. Bobby is livid with Suri got getting married in secret and without his presence. Suri explains the entire situation to Bobby. When Suri's colleagues self-invite themselves to his home for a party, Taani cooperates, comes out of her room and attends to guests. Taani doesn't let anybody know about the issues in her and Suri's marriage. Suri tells Taani that he has never been in love and has no expectations from Taani. For him, Taani maintaining his dignity in front of society is also love.

Suri continues to indulge her every desire to keep her happy. This includes frequent visits to the cinema to see song and dance films which appeal to Taani's fantasies about romance and her passion for dancing. Suri even buys a new car for Taani's convenience. Taani soon asks for Suri's permission, which he grants, to take an expensive dance class with the company Dancing Jodi to escape her mundane life at home.

During one visit to the cinema, Suri feels inadequate in comparison to the strong, masculine images that Taani admires and later asks his childhood friend Balwinder "Bobby" Khosla (Vinay Pathak), a hair-saloon owner, for advice on how to win her love. Bobby is eager to help and suggests a complete makeover including removing his mustache, changing his hairstyle, and giving him a new set of clothing including a pair of sunglasses.

Suri is thus transformed into the swaggering, loud, rude, and fun-loving "Raj", named by Suri after the hero in the movie that Taani had admired. He joins the dance class and by chance or, as he believes, by divine intervention becomes Taani's partner in the competition. When Taani sees him at the dance training center, she does not recognize him in his new look. Raj starts out by being very nervous around Taani and only talks in sentences that are titles of popular Bollywood movies.

Raj wears the most colorful and gaudy clothes to the dance class to maximize the contrast between him and Suri. Raj is very direct in his approach to Taani, which makes her uncomfortable and she tells Raj that she does not like him flirting with her. Despite Raj's initial crudeness a result of Surinder's inexperience with women and his attempt to emulate the "cool" images from movies he and Taani become friends as they work together on their dance routine.

Raj stays with Taani in the evenings but disguises himself and returns home as Suri. This continues for several days, and Taani begins to feel attracted to Raj. Suri feels encouraged when Taani does not tie a Rakhi (holy thread) on "Raj's" wrist during the festival of Raksha Bandhan (for to do so would indicate that she thought of him only as a brother). Thus, after a period of time, Raj declares his love for her.

Suri's ruse poses a dilemma for both of them. Taani enters into a period of internal conflict, desperately wanting to escape from her despair-filled life through finding a new person to love. Yet despite wanting to escape her loveless marriage, Taani feels compelled to stay with Suri due to the promise that she made to her father.

Suri also faces an extraordinary paradox: Taani's sheer misery as his wife in contrast to her delight with his fabricated alter ego "Raj." He thus attempts to win Taani's love as Suri, an act which only alienates her further. She eventually runs away to find Raj in order to tell him the predicament she is in, hoping he will help her. He offers to elope with her, which she agrees to tearfully. They set the date for their elopement to the next night, the night of the competition.

On the day of the competition, Suri takes Taani to the Golden Temple in order to garner God's blessings for her competition that night--and internally, also for her life with Raj. While there Taani has an epiphany in which she believes God has shown her a sign that tells that her marriage to Suri is divinely inspired. For the first time she reflects on her husband and becomes aware of the strength and integrity of Suri's character.

Taani thus tells Raj that she cannot run away with him. She leaves him in what appears to be a state of shock with tears in his eyes. When the time comes for their performance Taani is stunned to see Suri, rather than Raj, join her on stage. It is at that moment that Taani grows to love Suri (rather than Raj) as she discovers his passionate love for her.
