The film is about this not so perfect family, where each of these members have their own flaws. It is basically a story about two brothers, a very successful Rahul (Fawad Khan) and an under-achiever Arjun (Sidharth Malhotra), who come to Coonoor, a hill station in Tamil Nanu to visit their grandfather (Rishi Kapoor).
Rahul is a successful novelist who is the ideal son of the family, the golden boy who is perfect, nice and very loving. Meanwhile, Arjun is the struggling, odd or say disreputable member of the family. Like any two siblings, these brothers also have love, rivalry and a bit of jealousy amongst each other, which is shown in a very subtle way by the director. Tia (Alia Bhatt) has a typical girl next door character that one will instantly fall in love with and adore throughout.
