U.S. Marine Tommy Riordan returns home to confront his father, Paddy Conlon, who is now a recovering alcoholic. Despite Paddy's attempts at redemption through Christianity, Tommy is filled with resentment over his father's past abuse.

The day after his return, Tommy visits a local gym where he demonstrates his incredible fighting skills. He knocks out professional fighter Pete 'Mad Dog' Grimes in just under thirty seconds, and the knockout goes viral, showcasing Tommy's potential.

Tommy learns about the Sparta mixed martial arts tournament, which offers a staggering prize of $5,000,000 for the winner. Hoping to provide for his deceased friend's family, Tommy reluctantly approaches Paddy for training, with strict terms in place regarding their relationship.

Tommy's older brother, Brendan Conlon, is introduced as a high school physics teacher facing financial hardship. Pressured by medical bills for his daughter's heart surgery, Brendan contemplates returning to the fighting ring despite the risks involved.

After being suspended without pay, Brendan seeks to earn money by fighting again. He enlists the help of Frank Campana and begins competing in smaller venues, gradually building himself back up for a chance at the Sparta tournament.

When a contender in the Sparta tournament is injured, Brendan seizes the opportunity and persuades Frank to enter him. This unexpected turn reinvigorates Brendan's fighting career, giving him a shot at the desired large prize.

At the Sparta tournament, Brendan is confronted with the harsh reality of competing against his brother Tommy. Their shared history surfaces, particularly Tommy's resentment towards Brendan for abandoning their mother during her terminal illness.

The viral video of Tommy's impressive victory over 'Mad Dog' catches national attention. A Marine he saved in Iraq shares the footage, turning Tommy into an unexpected hero and garnering support from both fans and the U.S. Marine Corps.

As Tommy gains fame, troubling military records come to light that reveal his desertion after his unit was killed in friendly fire. This revelation casts a shadow on his newfound popularity, leading to impending legal consequences after the tournament.

Over the course of the tournament, Brendan, though physically outmatched, relies on his Brazilian Jiu-Jitsu techniques to secure victories. He stuns the audience by forcing the Russian champion Koba to tap out in the semi-finals, unexpectedly advancing to the finals.

As the final match approaches, tensions between the brothers escalate. Paddy's struggles to connect with Tommy culminate in a relapse into drinking, demonstrating the fraught family dynamics at play just before the climax of the tournament.

In the climactic final match, Tommy and Brendan face off, unleashing years of bottled emotions. Despite Tommy initially holding the upper hand, an injury changes the dynamics, and Brendan fights fiercely to win in a heartfelt culmination of their struggles.

As they grapple in the final moments, Brendan expresses his love and regret to Tommy. The match serves not just as a competition but as a painful yet healing encounter for the brothers, leading to Tommy's eventual submission and a bitter-sweet reunion.

After the match concludes, both brothers emerge united from the tournament, finally addressing the deep-rooted issues between them. Paddy watches proudly, signifying their tumultuous journey towards understanding and reconciliation.
