The film opens with Earl Stone (Clint Eastwood), an enthusiastic daylily grower who has garnered numerous accolades, facing a pivotal moment in his life. His daughter Iris (Alison Eastwood) is preparing for her wedding, while Earl's granddaughter Ginny eagerly hopes her grandfather will attend her birthday celebration. However, Earl’s ex-wife Mary Stone (Dianne Wiest), always the pragmatic voice, understands that Earl is likely to let the family down once more, a prediction that he fulfills with his familiar disregard.
A decade later, Earl's flower business struggles due to the rise of online competitors, putting his home at risk of foreclosure. During Ginny's birthday party, Iris confronts him, prompting Mary to realize that Earl is avoiding taking responsibility amidst the chaos in his life—a fact made evident when she looks inside his dilapidated truck, filled with discarded belongings.
At the party, an acquaintance hands Earl a business card, suggesting a way to improve his financial situation. Tempted by the promise of quick cash without questions, Earl soon gets involved in a shadowy operation. A garage becomes the base for his new job as he’s tasked with delivering an unmarked duffel bag to an undisclosed location. Following the strict instructions, he drives, parks, and returns within the hour to find a cash-filled envelope in his glove compartment, marking the beginning of his foray into illegal work.
Meanwhile, the Drug Enforcement Administration (DEA) takes notice, assigning Colin Bates (Bradley Cooper) to dismantle drug trafficking routes threatening the nation. Partnered with Michael Pena, Bates dives deep into the criminal underworld, setting his sights on taking down cartels.
Earl’s newfound income allows him to buy a flashy new truck, which he proudly showcases at the local VA, receiving scorn from a volunteer mourning the recent disaster there. A serendipitous meeting at the VA awakens a sense of responsibility in Earl, prompting him to attend Ginny’s wedding even though he’s been ostracized.
At the reception, Mary offers invaluable advice, reminding Earl that true change requires patience and effort, not overnight success. His renewed sense of self pushes him forward into additional clandestine missions, and he earns the admiration of his Mexican contacts, who nickname him "El Tata," recognizing his remarkable skills as a 90-year-old mule.
The grand reopening of the VA is a significant event for Earl, who, through acts of selflessness, earns newfound respect, even providing for Ginny's education, which culminates in an emotional graduation ceremony. Despite this, Iris remains distant, although Mary starts to rekindle their connection amidst health struggles that loom over them.
As the DEA intensifies its pursuit of "El Tata," Earl's success continues to grow, and a chance meeting with Bates in a coffee shop presents an opportunity for reflection. Earl shares heartfelt wisdom: > "Don't be like me," a stark reminder of life’s important priorities as turmoil swirls around him.
Invited to a lavish celebration in Mexico by cartel leader Laton, Earl momentarily enjoys his newfound status, but soon realizes the dangers that come with it, especially when Laton’s henchmen enact a ruthless retribution that elevates Earl’s standing. Under the new, profit-driven leadership, pressure mounts to maintain the flow of illicit activities at any cost.
As Mary returns home for hospice care, the impending nature of her fate casts a long shadow over Earl, who grapples with his choices and seizes a final chance to escape the cartel’s grip—vanishing from their radar, leaving both American and Mexican law enforcement on high alert.
In a deeply moving display of love, Earl stays by Mary’s side until her last moments, attending her funeral with profound sadness. Iris, sensing an opportunity for reconciliation, invites him to Thanksgiving dinner, yet Earl finds it hard to escape his tumultuous past and resumes his perilous drug runs.
When the cartel tracks him down to a truck stop, Earl's brutal beating serves as a harsh warning—but the remembrance of Mary’s funeral humanizes him in their eyes. The new boss initially calls for his assassination, yet his underlings plead for his life, securing him a reprieve contingent on one last task.
As Bates closes in, Earl's freedom eventually slips away as he’s captured, leading to a courtroom drama where his lawyer desperately paints him as a desperate veteran striving for his family's sake. In a shocking turn, Earl steps up to take accountability for his actions, guilt etched across his face. After his sentencing, his daughter and granddaughter come forward to console him with a tender kiss, symbolizing the enduring bond between them.
Ultimately, in prison, Earl finds solace in tending to a garden of daylilies, nurturing their beauty as a powerful reminder of hope and redemption—even in the darkest times.
