A gripping confrontation unfolds as street fighting issues are thrust into the spotlight in Mumbai. The sports chairman, Peter Braganza, played by Kiran Kumar, expresses a bold vision to legalize street fighting and establishes a league known as the Right 2 Fight (R2F).
Meanwhile, in prison, Garson "Gary" Fernandes, portrayed by Jackie Shroff, is released after serving his term as a recovering alcoholic. His younger foster son, Monty (Sidharth Malhotra), picks him up, but their reunion starts on a sour note when Monty resents his father’s inquiry about his elder brother, David (Akshay Kumar). The tension escalates as Gary clings to the memories of his deceased wife, Maria, and exhibits a fierce protectiveness over her belongings.
David, now working as a physics teacher, is struggling to provide for his daughter, who suffers from a kidney ailment. To fund her medical needs, he returns to his roots as a fighter, igniting frustration in his wife, Jenny (Jacqueline Fernandez), who fears for his safety. Amidst this, Gary's longing for Maria intensifies; he begins hallucinating about her and acts out violently in self-loathing, prompting Monty's desperate attempts to comfort him.
Gary’s desire to reconnect with David results in a heated encounter, revealing family secrets. It’s unveiled that Monty is actually Gary's illegitimate child, a truth that alters the dynamics of their relationships. The brothers had once shared a loving bond, overshadowed by the tragic events orchestrated by their father's struggles with alcoholism.
In a heartbreaking flashback, a drunken Gary mistakenly calls out to his mistress, Sarah, instead of Maria, igniting a tragic confrontation that culminates in Maria’s accidental death. In the aftermath, Monty and David are driven apart by grief and anger, each bearing the burden of their family's past.
As David's past as a street fighter resurfaces, he loses his teaching job, prompting Monty to pursue his own fighting dreams. Guided by the fight agent, Suleiman Pasha (Ashutosh Rana), Monty enters the ring, initially experiencing defeat but soon emerging victorious after a rematch, thereby gaining recognition from Peter for R2F.
His ascent to fame skyrockets as Monty evolves into a social media sensation. Meanwhile, David also dedicates himself to fighting, slowly regaining his footing with Suleiman's support. R2F becomes a global sensation, drawing in fighters from every corner of the world. Monty's remarkable journey leads him to a face-off against a vicious opponent, Luca (Conan Stevens), where he shocks the audience and secures a place in the finals.
David’s path mirrors Monty’s, as he navigates through challenges, ultimately leading to a climactic showdown between the two brothers, whose identities as family are revealed to the public, drawing enormous media attention. As tension rises and emotions clash within the arena, Gary watches on, plagued by guilt for the discord his actions have caused.
The final bout between Monty and David unfolds violently, filled with familial anguish and unresolved feelings. Monty belligerently pushes through the pain, but as David witnesses his brother’s suffering, he wrestles with his conscience, pleading with Monty to cease fighting. In a poignant moment, Monty reminds David of their shared loss, declaring that Maria was not just David’s mother but also his.
Through tears, David realizes the pain he inflicted upon Monty and ultimately extends an apology, leading to a heartfelt moment of reconciliation. Just as they were on the brink of resolution, the fight continues, symbolizing their tumultuous journey towards healing and brotherhood, culminating in a bittersweet victory as David embraces Monty, grieving yet celebrating their newfound bond.
