Brad Pitt accidentally runs a red light, culminating in a severe car collision with a mobster's vehicle. This incident catches the attention of the authorities, leading to a shocking discovery of a live body stashed in the trunk, foreshadowing a downward spiral into the criminal underworld.

As a result of the collision, the mobster receives a hefty five-year prison sentence. Pitt, now bound by obligation, must work for the mobster to settle the debt that fell into his lap due to his unfortunate mistake.

Julia Roberts, portraying Pitt's girlfriend, grows increasingly frustrated with their strained relationship. Eager to escape to Las Vegas, she struggles to understand Pitt's need to complete one final job for the mobster to ensure his safety.

In a dramatic emotional clash, Roberts decides to end their relationship, choosing to head to Vegas independently. Pitt, burdened by his obligations, begins his reluctant journey to Mexico to confront the mobster's demands.

Upon arriving in Mexico, Pitt is tasked with retrieving a notorious gun known as 'The Mexican.' He successfully obtains the weapon, but during a local celebration, tragedy strikes when a stray bullet leads to the death of the man who sold him the gun.

In the ensuing chaos after acquiring the gun, Pitt discovers that his car has been stolen with the gun inside. This revelation prompts a frantic pursuit as he desperately tries to recover his lost possession amidst the tumult.

As Roberts makes her way to Las Vegas, she faces an unexpected threat in a restroom when a gunman attempts to take her hostage. Just in the nick of time, she is rescued by James Gandolfini, who claims to be sent by the mobster to protect her.

Roberts and Gandolfini begin their journey together towards Vegas, experiencing unexpected twists along the way, including a romantic interlude involving a gay postal worker. Their joy is abruptly interrupted when the initial gunman returns, leading to a pivotal and violent confrontation.

In a tense showdown, Roberts and Gandolfini manage to confront the gunman, but their victory is marred by the tragic loss of the postal worker, who is thrown from a balcony during the chaos. This encounter profoundly impacts their journey and resolve.

Meanwhile, Pitt's troubles escalate as he loses the gun he acquired and faces an assassin sent to eliminate him. Despite managing to outsmart the assassin, Pitt finds himself hindered by a passport issue that complicates his escape from Mexico.

In an emotionally charged moment, Roberts confronts Pitt, leading to tension-filled interactions. During a misfortunate tire-change, Gandolfini unexpectedly draws a gun on Pitt, resulting in a cabin standoff that changes the course of their lives.

As the standoff escalates, Pitt cunningly realizes Gandolfini's true intentions, leading to a tragic yet decisive moment when he fatally shoots Gandolfini. This confrontation leaves a deep scar on both Pitt and Roberts, reshaping their perspectives.

After the chaos settles, Pitt confronts the original mob boss, Gene Hackman, who reveals the tragic history behind 'The Mexican' gun. This backstory serves to deepen the narrative's thematic layers of sorrow and betrayal, shaping their destiny.
