ITTEFAQ is the story of a two strangers who meet one night amidst killings and double crossings. Vikram Sethi (Sidharth Malhotra) is an acclaimed writer from London who is India for the launch of his third book. He goes to the hotel room post the event and finds that his wife Katherine (Kimberley McBeath) is no more. He calls the cops who try to frame him for the death. A paranoid Vikram runs away and takes refuge in the house of Maya (Sonakshi Sinha). When cops reach Maya’s residence, they realize that even her hubby Shekhar Sinha (Samir Sharma) is dead and Vikram is accused of murdering him. Dev Verma (Akshaye Khanna) is given the charge of investigating this high-profile case. Vikram maintains that he’s innocent and that he neither killed Katherine nor Shekhar. Meanwhile, Maya alleges that Vikram killed Shekhar. Dev is torn between the two versions of the story, and will not settle till he finds out what happened that night. What happens next forms the rest of the film.
