Siddharth "Sid" (John Abraham) works in a bookstore in London named Kagaz Ke Phool with his Pakistani friend Omar (Raghu Ram). His girlfriend Krutika (Manasi Scott) never leaves a chance to dominate him. The twist comes when Sid starts getting calls from people who are attempting suicide as his number was mistakenly printed on fliers of an Indian suicide helpline and later on he takes on the counselling job.
One night he gets a call from Mishka (Pakhi Tyrewala) who had a bad relationship and is on the verge of taking her life. Sid and Mishka get talking and suicidal feelings are thrown over London's Tower Bridge. They become phone friends and Sid knows who Mishka is when she visits his bookstore. Unaware that Sid aka Fidato is the one who takes up her call and consoles her, she befriends Sid upon Fidato's advice. Then starts the meetings of Sid and Mishka where he impresses her by telling her all the things which she used to tell Fidato. But one fine day, Kabir (ex-boyfriend of Mishka) springs up from no where, and introduces his new girlfriend to Mishka, meanwhile Sid arrives and in their chat, he calls Kabir by his name. This makes Mishka wonder whether Sid and Fidato are same or not. This leads her to go to suicide helpline center and confirm whether Sid is Fidato or not and here she is misled.
