Akash (Ranbir Kapoor) and Kiara (Priyanka Chopra) meet on a bridge in Manhattan under unfavourable circumstances. They both are trying to throw themselves down in a suicidal bid, being unable to cope with the hurdles of life any longer. But jump, they can't, and end up together in a pact which sees them spending twenty days together before they take the final plunge. So what happens in those twenty days? A road trip to Vegas, followed by loads of wish fulfilment.... More importantly, are they able to carry off the suicide pact? Keep guessing.
