Getting to the storyline *no spoilers*: Naina (Taapsee Pannu) is being blackmailed. Right as she was getting ready to pay the ransom, she gets knocked down inside a hotel room. When she wakes up, her lover is dead and she is one of the top suspects. While her lawyer (Manav Kaul) is doing everything possible to bring her justice, Naina is now edgy and worried. Up comes Badal Gupta (Amitabh Bachchan) who specializes in acquiring witnesses. All Badal needs is the whole truth, and then he will give her the best legal defence. Given Naina’s life is in tatters, with her lover dead and marriage in shambles, Gupta is her only hope.
