Blackmail Hindi Movie Online HD, As the name suggests itself, Blackmail is the story of a bored and in-debt husband who devises a bizarre idea when he finds out that his wife is having an extra marital affair. Dev Kaushal (Irrfan Khan) works for Boss DK (Omi Vaidya) at My Handy, a toilet paper company. He is married to Reena (Kirti Kulhari) and their marriage has lost the spark. He prefers being in the office till late and playing games on the computer rather than going home early and spending time with his wife. Dev’s colleague Anand Tripathi (Pradhuman Singh Mall) advises him to go home early one day, buy flowers and surprise his wife. Dev likes this idea and goes home early only to find Reena sleeping with her ex-boyfriend Ranjit Arora (Arunoday Singh). On the other hand, Dev isn’t going to get a pay raise from DK and he has mounting debts. Hence, he buys a prepaid SIM card and blackmails Ranjit anonymously. Dev asks him to pay Rs. 1 lakh or else he’ll tell the truth to Dev! Ranjit is married to Dolly Verma (Divya Dutta) who suspects that Dev is cheating on her. Ranjit is broke and he asks for the blackmail amount under the pretext of starting a new business. Dolly hands him the said amount and he in turns hands it to Dev. Dolly’s father (Nav Ratan Singh Rathore) then asks Ranjit to return the Rs. 1 lakh that he took from Dolly and threatens him with dire consequences. With no other option in hand, Ranjit creates an anonymous email account and blackmails Reena into giving Rs. 1.20 lakh! He uses the same kind of words used by Dev in the blackmail message so that Reena would assume that it’s the same blackmailer. Reena has only Rs. 30,000 as savings and desperate to arrange the balance amount, she asks none other than Dev for Rs. 90,000! Dev agrees to give her the money but also realizes that he’ll be in debt again! So he asks for more money from Ranjit! As a result, Ranjit takes the Rs. 1.20 lakh from Reena, takes Rs. 20000 for himself and gives away the remaining amount to Dev! While this merry go around is going on, Dev confesses about blackmailing his wife’s lover to Anand. Anand in turn blurts out about it to Prabha (Anuja Anil Sathe), who has joined My Handy recently and whom Anand crushes on. Now Prabha starts blackmailing Dev for money and threatens that she’ll tell the truth to Reena if he doesn’t pay her up. What happens next forms the rest of the film.
