The film starts off with the introduction of a ‘totally safe’ Gaurav (Sidharth Malhotra) and an ‘action-packed’ Rishi (Sidharth Malhotra). While Gaurav works in the marketing department of a leading software company, Rishi works in ‘Unit X’ as the ‘Man Friday’ of Colonel (Suniel Shetty), a self-centered high profile badman, who does not think twice before bumping off any of his henchmen for his own benefit. The ‘future-perfect’ Gaurav nurtures his long cherished dream of having his own lavish house so that his children can play at ease. Even though he is in love with his colleague Kavya (Jacqueline Fernandez), he does not muster the courage to confess his love for her. On the other hand, after having worked for so many years for Colonel, the trigger-happy Rishi decides to call it a day and have a peaceful life, minus any violence.

When Rishi tells Colonel about his decision to leave ‘Unit X’, the initially reluctant Colonel allows him to leave the outfit, but, only after completing one last task. Wasting no time, Colonel instructs his men to bump off Rishi once the task is completed. Do Rishi and Gaurav ever cross each other’s paths, what connection do Rishi and Gaurav have with each other, what happens to Rishi and Gaurav in the end, does Gaurav become successful in realising his dreams and does Rishi become successful in completing the given task by the Colonel, is what forms the rest of the film.
