Fifty-something Arkansas redneck Earl Pilcher Jr. embarks on a life-altering journey upon discovering that his biological mother was black and that he has a half-brother named Ray, who resides in Chicago. Determined to connect with Ray, Earl drives his pickup to the windy city, only to find that their reunion is anything but warm. Ray harbors resentment, blaming Earl's racist father for their mother’s tragic passing, which now casts a shadow over his feelings towards Earl.
After an uncomfortable confrontation, Earl's plans are derailed when his pickup gets carjacked, resulting in a severe head injury. In a twist of fate, Ray, now a Chicago cop, is coerced into taking Earl from the hospital back to his home under the doctor's orders that Earl must stay awake. To mask their family relationship from their Auntie T., Ray fabricates a tale about being Korean War buddies with Earl. However, Auntie T., who is blind, readily sees through the ruse, recognizing Earl's true identity.
When Ray’s son, Virgil, arrives from his job as a city transit bus driver, he is confronted with the unexpected sight of Earl sleeping on his couch. Suspicion drips from Virgil as he demands to know who this stranger is. Fortunately, Auntie T. steps in, insisting that the truth be revealed. This revelation prompts Earl to consider leaving in search of a motel. However, an argument ensues between Earl and Ray, leading to a physical scuffle. The confrontation takes a stark turn when Earl makes a racially charged remark, igniting Ray's fury. As Ray storms off, he declares, "If you need any more help, don't call me. I'm through helping you!"
That night, hit hard by his choices, Earl seeks refuge under a bridge alongside a group of homeless individuals. Meanwhile, Ray, scrapping his anger after a stern talk from Auntie T., attempts to find Earl, reaching out to the police dispatcher to keep an eye on his brother. The next day brings mixed news when Virgil learns that Earl has been discovered.
The family unites with Virgil's ex-wife, Ann, and their daughters, Kindra and Danielle, for a picnic. During this gathering, Earl gains insight into Virgil's past and the dreams that were dashed after a knee injury curtailed his football career. This moment fosters a deeper bond as Earl urges Virgil to seek hope and pursue positives in life. Virgil, initially resistant, begins to reflect on Earl's encouraging words.
Back at home, Auntie T. presents Earl with a photograph of their mother and recounts the heartwarming yet bittersweet tale of Earl's birth, revealing a moment where Ray cradled Earl as a newborn and proclaimed, "This is my baby." The story touches both brothers deeply, leading them to confront their shared past.
In a poignant turn of events, Ray takes Earl to reclaim his stolen truck from the police impound lot. Despite its rough condition—marked with bullet holes from a robbery—the truck signifies a path back to their roots. Together, the brothers set off on a heartfelt journey back to Arkansas to pay respects at their mother's grave, embarking on a healing journey marked by their newfound connection.
