Jagdishwar Mishra fondly known as Jolly (Akshay Kumar) is a jolly good lawyer who works as an assistant to Lucknow's top lawyer. He is an ambitious middle class family man who immensely loves his demanding yet loving wife Pushpa (Huma Qureshi). To fulfil his father's dream of owning a chamber, Jolly tricks a pregnant widow Heena Siddiqui (Sayani Gupta) for money. The lady who seeks justice for her husband's murder, commits suicide, leaving Jolly in utter shame and guilt.

Jolly then takes it on himself to fight for justice going against the system and the powerful. The layers of the case unfold and Jolly faces tremendous obstacles in the path of justice created by the culprits to hide their hideous crimes.
