When 24-year-old Veronica (Deepika Padukone) and Meera (Diana Penty), 23, start living together during the summer in London, they have very different agendas. Meera is awkward, introvert and recovering from a hoax marriage to Kunal Ahuja (Randeep Hooda) who has duped her off her life-savings by using the pretense of setting up a base for them in London. She is spending her time under Veronica’s roof until she can get some footing and find a job in this foreign land. Veronica, on the other hand, is a wild-child, impulsive, constantly looking for distractions to escape facing issues of a troubled upbringing. Being poles apart brings the two close, forging a loyal and solid friendship. Soon Gautam, 32, (Saif Ali Khan) enters their lives, moves in with them and has a whirlwind relationship with Meera’s. Meera does love Gautam because his don’t-give-a-damn attitude reminds her of her husband who had conned her into coming to London in the first place.
