The film is all about a group of five college friends — Shyam, Emaan, Pooja, Priya and Irene. The friends gather for Emaan's wedding, years after everyone has parted ways.

The film starts with Pooja leaving the United States to go to Indian cricketer and her friend Emaan's wedding. Meanwhile, back in India, everyone else is helping Emaan with the preparations for his wedding and catching up with their long-lost college friends. The movie goes through series of flashbacks of old memories during their college days. Emaan and Irene meet for the first time after years. It turns out that they were once in love during their college days but Irene, who is from an unstable family, decides to part ways with Emaan after he loses focus on his long time goal of becoming a successful cricketer.

Another flashback occurs when Shyam gets reminded of Pooja. She is a fun-loving tomboyish and naive girl, who is best friends with Shyam. Shyam realizes that he is in love with Priya, but on the other hand, Pooja realizes that she is falling for Shyam. Shyam and Pooja had respectively decided to propose their love interests on the coming Valentine's Day. But on that day, Pooja learns beforehand that Shyam is in love with Priya instead. Heartbroken by what she has just learned, she decides to keep her love for him a secret. When Shyam proposes Priya, she rejects his love as she believes in a more traditional approach towards finding a life partner. She reveals to him that she will be getting married, right after their graduation, to the man of her parents' choice. Pooja eventually goes to the US for her higher studies and settles down there. Shyam has also tried to move on since then and becomes a fashion designer.

The film transitions back to the present on Emaan's wedding day. Everyone attends his wedding as Pooja finally arrives. She is no longer the same girl she was back then, as she is much more mature now and not as tomboyish as she was back then. Over sometime, Shyam has come to realize that he missed Pooja's presence and is much fond of her now. He realizes that he had failed to appreciate her all those times when she was there with him. The day after Emaan's wedding, Pooja leaves to catch her flight back to USA. Right before her departure, she decides to pass Shyam the Valentine's Day card that she had wanted to hand him during their college days and reveals her love for him. Shyam realizes that Pooja is the one that was meant to be for him and not Priya. The movie ends with Shyam accepting Pooja's love for him.
