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 and he is so fed up.

The twist comes when Sid starts getting calls from people who are attempting suicide as his number was mistakenly printed on fliers of a suicide helpline, and later on he takes on the phone counselling job.

One night, he gets a call from a beautiful and lonely sad Mishka (Pakhi Tyrewala) who has had a bad relationship with her ex bf Kabir, 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 coincidence, Mishka comes to Sid's bookstore to buy some books, and Sid falls in love with her but wants to hide his Fidato identity so Sid pretends he has a stammer. Mishka befriends Sid not knowing that he is Fidato, her phone friend-counselor.

Then Sid and Mishka get closer and bond closely where Sid takes the unique opportunity to impress her by telling her all the things which she used to confide in her phone friend Fidato.

One day, Fidato mentions Kabir by name by mistake whereas Mishka had only mentioned Kabir name to Sid, not Fidato. things patch up.

However, another twist arises when one fine day, Kabir (ex-boyfriend of Mishka) springs up and apologise to Mishka, and when Mishka ignores him telling him she is with Sid, he becomes suicidal.

When Mishka sees Kabir has true love for her, she can't bear the separation any longer and they get closer much to Sid's disappoinment as he had fallen in love with Mishka.

The final straw comes in when Mishka's neighbor is suicidal takes poison and calls Fidato help line, and Fidato recognized that it is Mishka's neighbor and immediately calls Mishka in the middle of the night to call 999.

Later on, on the London Bridge, Sid and Mishka finally end their differences and the film ends on a happy note when sid any how went one side from another to take the last chance provided by Mishka although the bridge gates were closed. At the end they two hug each other & the movie ends with a slow romantic song in the background.

The movie released on 22 October 2010. Earlier it planned to release on 4 July and 15 October, but was delayed since the re-recording of the background score by Rahman took more time than planned.

The original score and songs of the film were composed by A. R. Rahman with lyrics penned by Abbas Tyrewala. He composed eight tracks for the film; however, a track by Shaan and Sunidhi Chauhan was not featured in the film or soundtrack album. There were rumours that KK and Adnan Sami have recorded songs for the album, but this did not happen. Rahman recorded some of the background score at his K. M. Musiq Studios in Los Angeles. Rahman wrote on a social networking website, "Recorded with a Los Angeles jazz quartet, a couple of whom have played with the likes of Barbra Streisand and Billie Holiday." A few of the songs were recorded in London, while the rest was recorded in Chennai. There were reports that the re-recording of the score took more time than planned and this led to the delayed release of the movie.

Warner Bros. filed a case of copyright violation alleging that the movie was copied from their television series Friends. The producer of the film, Madhu Mantena, responded that it was not true and that the film had nothing to do with Friends; director Abbas Tyrewala has also denied the allegations.^[11]

Critical response

Jhootha Hi Sahi has received mixed critical responses. On the review-aggregation website ReviewGang, the film scored 5.0/10 based on 4 reviews.^[12] Nikhat Kazmi of The Times of India rated it 3.5/5: "The script has a few teasing twists and turns that do not let it fall into the rut of predictable run-of-the-mill romances".^[13] Aniruddha Guha of DNA rated it 2/4: "The film may have its moments, but not enough to leave you with a smile at the end. Not even recommended as a date movie".^[14] Sukanya Venkatraghavan of Filmfare wrote, Jhootha Hi Sahi is like an amateur college play where everyone is trying too hard and the writing is just plain cocky, with no depth or direction".^[15] Sukanya Verma of Rediff wrote, "John's the best, forget the rest". She gave a 2 out of 5 rating to the movie.^[16] Mathures Paul of The Statesman gave the film 2 out of 5 stars, noting, "It really doesn’t matter if Abraham lost a few stones to play Sid, if Pakhi is a good scriptwriter (though she looks like a middle-aged aunt with two left feet), AR Rahman is the music director and Abbas Tyrewala's last film was the modestly successful Jaane Tu Ya Jaane Na. They all work in different directions".^[17]
