Bholaa is a gripping action film that follows the intense journey of a tough and determined man Ajay Devgn who is released from prison after serving a long sentence. The story begins with SP Diana Joseph Tabu, a dedicated police officer, successfully capturing members of the notorious Sikka Gang and confiscating a staggering haul of cocaine worth ₹1,000 crore. The case is complicated by the presence of Abbas Ali, also known as Raunak, an undercover officer working closely with Ashwathama “Ashu” Deepak Dobriyal, the reckless co-leader of the gang. Raunak secretly provides crucial intel about Ashu to Diana, setting the stage for a tense cat-and-mouse game.
Meanwhile, Ashu enlists the help of a corrupt NCB officer, Devraj Subramaniam [Gajraj Rao], who conspires to drug the police officers attending a farewell party organized by IG Jayant Malik [Kiran Kumar], by instructing Deep Singh Lokesh Mittal to add rohypnol to their drinks. Although Diana, who is on medication and wisely chooses not to partake, notices the suspicious activity, everyone else is drugged and soon falls unconscious.
In the midst of this chaos, a prisoner named Bholaa—a rugged and skilled individual—emerges as a pivotal figure. Restricted from his past life, he is released from custody, and Diana desperately tries to persuade him to drive a truck carrying the heavily sedated cops to the hospital and, later, to the Laalganj police station. After initial resistance, Bholaa agrees to help, knowing the gravity of the situation. As they set out, Ashu, furious and desperate, places a bounty on Diana and her team, escalating the danger.
Throughout their journey, Bholaa, accompanied by his loyal sidekick Kadchi, faces relentless attacks from various gangs sent by Ashu. With Deep Singh providing real-time intelligence from hiding spots, Bholaa fights off multiple goons, displaying his impressive combat skills. At the same time, Ashu's gang storms the police station, aiming to free Nithari, who was arrested with the cocaine stash, igniting a fierce confrontation led by Constable Angad Yadav. He has recently been transferred to Laalganj and is tasked with defending the station. When Ashu's gang arrives, trying to overpower the station’s defenses barricaded by Yadav and a group of students, a tense standoff ensues.
Diana carefully avoids releasing Nithari, realizing he has set a trap to manipulate her into releasing Ashu. Despite Ashu managing to breach the station temporarily and engaging in brutal fights, Yadav and the brave students manage to arrest him. In a tragic turn, one student, Chetan, is strangled to death by Ashu’s henchmen, emphasizing the high stakes and violence surrounding their operations. With quick thinking, Yadav kills Ashu during the chaos, and Diana calls for medics as the police and injured officers rally at a temple of Lord Shiva to wait for emergency help.
The story then shifts to a poignant flashback where Bholaa reveals his painful past: once a notorious gangster in Uttar Pradesh, he fell in love with a doctor named Swara [Amala Paul], who was tragically killed by the ruthless Chomu Singh [Abhishek Bachchan]. Before her death, Swara gave birth to their daughter Jyoti but was separated from her after Bholaa was sent to prison. This deep personal loss fuels Bholaa's fierce determination to protect his loved ones and seek justice.
Back in the present, as the injured officers are rushed away in an ambulance, Bhoora arrives, seeking revenge. Before a fight can erupt, Deep Singh stabs Bholaa, leaving him seriously injured. Meanwhile, Diana and Kadchi are captured, and Abbas Ali [Sanjay Mishra] is killed after his true identity is exposed. Miraculously, Bholaa regains consciousness and, fueled by a burning desire for justice, single-handedly takes on and kills the entire gang, including Deep Singh, wielding a powerful Trishul.
In a dramatic chase, Bholaa manages to rescue Diana, killing Bhoora in the process. Driven by pure resolve, Bholaa and his allies manage to escape through a secret passage, helping the students and Yadav to safety. With the cocaine destroyed in a fiery blaze, Ashu’s heavily reinforced gang finally breaches the police station. In a spectacular display of force, Bholaa unleashes destruction using a M134 Minigun, eliminating everyone in his path. Nithari succumbs to shock upon hearing the truth of Bholaa’s actions, and Devraj Subramaniam [Gajraj Rao], overwhelmed and guilt-ridden, takes his own life upon realizing Bholaa's hand in the events.
The story concludes with Bholaa reuniting with his daughter Jyoti [Hirva Samir Trivedi], driving off into the sunset with Kadchi and a loyal puppy, symbolizing a bittersweet victory and hope for the future.
In the mid-credits scene, the ominous figure of Chomu Singh learns about Bholaa's release from prison and begins planning his hunt, hinting at new conflicts to come.
