The first half of the movie is shown via narration by Dev's friend Vicky (RJ Vigneshkanth). Vicky is an apparent comedian who was encouraged by Dev (Karthi). What a mistake it was. The life of Dev is shown eventually to us. He is encouraged to love a girl by using tactics of social media and stalking. This method exposes him to Meghna (Rakul Preet Singh), a big businesswoman who made it big on her own. Dev is a boy and gets attracted at first sight but is reluctant to stalk a girl in this day and age. His clueless friends encourage him to stalk her anyways as it is a manly thing to do. As fate has it, he eventually sees her in India and throws away his ethics to try and win her heart.
