Siddharth "Sid" Arya (John Abraham) is an average man who owns a bookstore in London named Kagaz Ke Phool with his friends, Omar (Raghu Ram), a Pakistani and naive but jovial Amit (Omar Khan). His other friends include Omar's pregnant sister Aliya (Alishka Varde), her boyfriend Nick (George Young) and Uday (Prashant Chawla) who is gay. His girlfriend Krutika (Manasi Scott), an air hostess, never leaves a chance to dominate him and he gets fed up as a result, but tries his best to keep her happy nevertheless. One night, Sid starts getting calls from people at night who attempt suicide and learns from Suhana Malik (Nandana Sen), an NGO volunteer that his number was mistakenly printed on fliers of a suicide helpline, DOST India. Sid offers to volunteer willingly as he has some experience in convincing people and consoling them. He gets a call from Mishka (Pakhi Tyrewala), a beautiful but suicidal woman who was dumped by her ex-boyfriend Kabir (R. Madhavan), a writer, and is on the verge of taking her life. Mishka discloses her suicidal feelings and then they become phone friends. However, as a rule, Sid must keep his phone identity hidden so Mishka starts calling him "Fidato". As a coincidence, Mishka comes to Sid's bookstore to buy some books as instructed by Fidato. Despite the awkward first impression at the bookstore, Fidato insists Mishka that she befriend Sid, as it would make her happy and live on with life, to which she agrees. Sid/Fidato and Mishka get closer and bond closely through their night phone calls, where Sid learns that Mishka is a painter by profession and lives all alone, having given up her profession as it reminded her of the hard times with Kabir. Sid/Fidato consoles her and eventually Mishka gets better and decides to start life afresh, thanks to Sid. His friends also realize that Sid is truly in love with Mishka since he never happened to stammer when Krutika is around (Sid stammers whenever he talks to beautiful women, but not on the phone nor with his friends.) One day, Kabir happens to bump into Mishka while she is sketching. Kabir is shown to be a sadist, who takes any chance to see Mishka suffer, tries to make her feel lonely by introducing his new girlfriend Bhavana, but gets interrupted upon seeing Sid mingling with Mishka. Sid accidentally mentions Kabir by name whereas Mishka had only mentioned Kabir's name to Fidato and not Sid. He somehow handles the situation with Mishka and things patch up. Mishka suspects that Fidato and Sid are the same person since Sid accidentally mentions details that Mishka had only shared with Fidato. She goes with her friend Sushi (Anaitha Nair) to the DOST India office, where Sid convinces Suhana to hide his identity, no matter whatever she asks. Suhana reluctantly agrees and the plan succeeds. Sid introduces Mishka to his friends, who invite her to dinner, but Krutika intervenes that night, causing Mishka to become heartbroken upon learning that she is Sid's girlfriend. Sid convinces Omar to pretend he is Krutika's boyfriend and sorts things out with Mishka, while promising that he would never lie to her again. Kabir meets with an accident and sees this as an opportunity to snatch Mishka back from Sid as he becomes jealous of seeing them hanging out together. He lies to Mishka that he had gotten into a fight with Bhavana and Mishka is all he has. Mishka gets into a fix of choosing Kabir over Sid. Fidato tries to tell Mishka to avoid Kabir as he had only wanted Mishka back so that he can make her suffer. He then gets a call from Ankur, Mishka's neighbour who has a crush on her; he is suicidal due to his parents' quarrel and overdoses on sleeping pills. Fidato immediately tells her to call 999 and runs across the street to ensure that Ankur is taken to hospital. Mishka finds out that Sid is Fidato and breaks up with him, telling him that Fidato means "trustworthy". She moves in with Kabir, who tells her that he would take her to Paris, the place Mishka had longed to visit. Later Sid visits Ankur and tries to convince Mishka and openly tells her that he loves her, much to Kabir's dismay, and he gets beaten up by him. Mishka stops them and tells her that Sid is "a nobody", which gets him distraught. He then decides to go back to his friends. That night, Mishka and Kabir are en route to the airport when Mishka finally realizes Kabir's true intentions and her love for Sid. She tells Kabir that when she was suicidal and all alone, Sid had given her a reason to live and abruptly ends her relationship with Kabir. Mishka decides to patch up with Sid and calls him to meet her at the London bridge within 10 minutes to prove his love for her. Sid gets overjoyed and together with his friends, rush to the bridge where they are stopped by policemen. His friends distract the police, enabling Sid to reach the bridge, but finds that it had been raised and Mishka decides to leave. Sid does not think even for a second and decides to run to the other side and ju
