D. N. Tripathi, a lyricist writes a biography on Sanjay "Sanju" Dutt, comparing him with Mahatma Gandhi. Flabbergasted, Sanjay throws him out. The Supreme Court of India delivers its verdict regarding the 1993 Bombay bombings and sentences Sanjay to 5 years jail term for violating the Arms Act, 1959. His wife Manyata Dutt living with their 2 twin children approaches Winnie Diaz, a London-based writer, to write his biography and present his version of life to the public.Unwilling at first, Winnie is asked by Zubin Mistry, a real estate builder, to not write the biography, which intrigues her. She gets to know that he is a womanizer also and slept with over 200 girlfriends but Sanjay laughs and speaks out the truth. Winnie first interviews him, and his life is revealed in a flashback as the story goes to the past now. Sanjay's father Sunil Dutt plans to launch his career in Bollywood with Rocky (1981). Upset over Sunil's controlling behavior on set, Zubin "God" (Sanjay's then-friend) encourages him to try drugs for the first time. Sanjay soon discovers that his mother Nargis is suffering from pancreatic cancer; they head to New York for treatment. This incident furthers his descent into alcoholism and drug addiction. Sanjay meets Kamlesh "Kamli", a fan of Nargis in New York, and they become quick friends. He makes Sanjay stay away from his addiction. After learning of his girlfriend Ruby's fixed marriage due to his drug addiction, Sanjay relapses. Kamlesh convinces Ruby to register to marry Sanjay; but when she after realizing her love for Sanjay, she agrees and comes to the registration office. She finds that Sanjay isn't there; on reaching his house, she realizes that he is still a druggie, and leaves him. Nargis dies 3 days before the release of Rocky which takes an emotional toll on Sanjay who agrees to attend a rehabilitation center in the United States and recovers with the help of Sunil and Kamlesh eventually. On returning to India, he meets and beats Zubin for selling him drugs upon realizing that Zubin himself was consuming glucose. Back to the present, Sanjay's later life is narrated by now-estranged Kamlesh who Winnie tracks down in New York. He is at first reluctant since he has wasted many years of his life on Sanjay but finally agrees to tell her the story. In the 1990s, Sanjay turns to bodybuilding and his career in Bollywood greatly improves. He cheats Kamlesh upon sleeping with his Gujarati girlfriend Pinky but later the matter is solved. After the 1992 Babri Masjid demolition, Sanjay acquires 3 AK-56 rifles to ensure the protection of Sunil (who'd by then entered politics) and sister Priya Dutt. A series of bombings occur in Bombay shortly thereafter. For possession of illegal arms supplied by the D-Company supposedly to be trafficked for protection during potential communal rioting after the bombings, Sanjay is arrested in 1993. He is convicted and sentenced to jail for 5 years under Terrorist and Disruptive Activities (Prevention) Act (TADA), threatening his career. Further tarnishing his public image, the media labels him as a terrorist. Believing Sanjay to be guilty, Kamlesh severs ties with him. After its release in 1995, Sanjay appears in many flops. When his popularity begun to wane, he is forced to sign the title role in Munna Bhai M.B.B.S. (2003) by Sunil, who also features in the film as his father. It wins Sanjay the Filmfare Award for Best Performance in a Comic Role and his image improves, making Sunil proud. Shortly afterward, Sunil dies. In 2006, the Bombay High Court finds Sanjay guilty under the Possession of Arms Act, while not finding him to be a terrorist. He is arrested again in 2013 by the same verdict upheld by the Supreme Court of India. Sanjay convinces Winnie and Kamli of his innocence by blaming the media for falsely accusing him of terrorism. He is subsequently bailed in 2016 and finds out Winnie has completed writing his biography, Kuch Toh Log Kahenge (transl. People will keep saying something), named after one of Sunil's favorite songs from Amar Prem (1972). He exits the prison and reunites with Kamlesh and Manyata. Sanjay tells his children not to be like him but like Sunil. His life was Struggling but Sunil made him a great actor.
