It is September 1971, a period marked by the realization that the Vietnam War is a losing battle for the United States. Most soldiers, shaped by the ideals of the 1960s Peace Movement, share the sentiment that defeat has been a foregone conclusion for some time. Among them is Roland Bozz, played by Colin Farrell, a draftee with a profound opposition to the war. His unruly nature and blatant disregard for authority set him apart: he frequently disobeys orders and challenges his superiors.
On his journey, Bozz forms a strong friendship with fellow recruit Jim Paxton (portrayed by Matthew Davis), an aspiring writer documenting their experiences in a personal journal. Unlike Bozz, Paxton is a volunteer who took an active step to join the Army. Upon arriving at their post, Captain Saunders makes it abundantly clear that every soldier stationed at Fort Polk and in Tigerland will inevitably be deployed to Vietnam, declaring that any political concerns are irrelevant at this stage.
As the narrative unfolds, we see deeper layers of Bozz’s character. With an impressive knack for exploiting gaps in military bureaucracy, he devises clever strategies to help fellow soldiers avoid combat. This includes assisting a soldier who is not only a father but also supports a disabled wife, as well as another soldier named Miter (played by Clifton Collins Jr.), who enrolled in the army to prove his masculinity but quickly realized the gravity of his decision. At one crucial moment, a fellow soldier approaches Bozz for help, remarking, > "I was told if you don't want to go to 'Nam, you either pray to Jesus, or go see Roland Bozz." Here, Bozz reveals that his opposition to the war stems from a place of human compassion.
As the story develops, Bozz's natural leadership capabilities earn him the informal title of squad leader, often referred to as acting Jack. However, the atmosphere is tense due to another private in the company, Wilson (Shea Whigham), a racist bully who takes every opportunity to belittle Bozz and Miter, targeting those he views as "weak." Unlike others, Bozz stands up against Wilson, leading to a brutal confrontation. Paxton intervenes, which intensifies Wilson's animosity toward him.
During a live-fire exercise, Wilson threatens Bozz with a firearm, resulting in a desperate struggle. Ultimately, Bozz’s life is spared when the weapon misfires, leaving him with the option to hold Wilson accountable. Under pressure from their commanding officer, Bozz opts to have Wilson dismissed from the army instead of pursuing a court-martial, believing that Wilson's struggle with emotions has made him dangerous yet redeemable.
Afterward, the platoon is transferred to Tigerland, a meticulously designed training site mimicking Vietnam's harsh terrain. In a training scenario, Bozz and his squad role-play as villagers while pitted against Wilson’s squad, which aims to uncover a VC sympathizer. Eventually, as tensions grow, Wilson vows to kill Bozz, setting the stage for a climactic showdown.
Just as Bozz seems ready to flee to Mexico with assistance from some locals, he realizes that doing so would put Paxton in jeopardy, forcing him to reconsider his plans. The ensuing events culminate with a hazardous training drill where Wilson replaces blanks with live ammunition. When he opens fire during a simulation, chaos ensues, leading to Paxton being injured by an errant blank fired too closely. As the trainer intervenes, the dire situation escalates.
As the film wraps up, the platoon prepares to embark for Vietnam, with Paxton receiving a medical discharge due to his eye injury. In an emotional farewell, Bozz and Paxton exchange conflicted sentiments, with Paxton expressing an intent to write about Bozz’s journey. However, Bozz, in a moment of defiance, steals Paxton's journal and discards the pages as the bus pulls away, leaving Paxton scrambling to retrieve his work.
In a haunting final twist, Paxton learns that Bozz was reportedly killed in Vietnam, yet his official records remain ambiguous. Years later, he hears rumors of Bozz being spotted in Mexico, leading to questions about the truth behind his fate and the enduring impact of their bond.
