Charlie Baileygates is a gentle, unassuming state trooper from Rhode Island who has consistently been taken for granted by those around him, particularly by his unfaithful wife, Layla. Their relationship is troubled right from the beginning, especially when she embarks on a clandestine affair with their wedding limo driver, Shonté, who, despite his small stature, possesses a sharp intellect and a flair for surprises. Even in the face of his friends’ warnings about Layla's betrayal, Charlie remains oblivious, especially when she gives birth to triplets – Jamal, Lee Harvey, and Shonté Jr., all three of whom inherit their father's remarkable intelligence.
As time moves on, Layla finally leaves Charlie, leaving him to shoulder the responsibility of raising their children alone. Though the journey is fraught with challenges, the triplets grow to love and admire their father, who becomes their steadfast source of support. However, Charlie’s naivety continues to be exploited by the community, prompting him to develop a wide-ranging coping mechanism in the form of an alternate persona, Hank Evans, which surfaces during moments of extreme stress.
Unlike the timid Charlie, Hank embodies a rugged, assertive character reminiscent of Clint Eastwood's iconic roles. A psychiatrist suggests medication to control this alter ego. When Charlie’s commanding officer assigns him to escort the striking Irene Waters, who has been accused of a hit-and-run in Massena, New York, he feels it’s the perfect distraction from his troubles.
Irene argues that her mobster ex-boyfriend Dickie framed her to ensure her silence regarding his illegal dealings. On their shared journey, Charlie and Irene submit her case to two EPA agents in Massena. A shocking turn occurs when one agent falls victim to a hitman seeking to eliminate Irene, leaving Charlie reeling in helplessness.
In a frantic attempt to escape the situation, Charlie and Irene abandon their safety net by leaving behind Charlie's medication, unaware that this choice will soon lead to Charlie being viewed as the main suspect in the murder. With both FBI agents and corrupt police officers, Boshane and Gerke, who are on Dickie's payroll, out to capture them, their flight quickly becomes a spectacle for the media. As chaos reigns, Charlie's sons begin to suspect the trouble their father has found himself in, setting the stage for an exhilarating adventure that will truly test his courage.
Their odyssey back to Rhode Island creates an opportunity for Charlie and Irene to bond during this unexpected road trip. However, the volatile Hank threatens their safety with his reckless bravado. As they navigate these challenges, they pick up an intriguing figure named Whitey, an albino waiter with a murky history, who shares alarming tales about his family’s demise, only serving to heighten Hank's paranoia. A pit stop at a run-down motel reveals Hank manipulating the situation, impersonating Charlie to coerce Irene. The explosive confrontation that follows allows Charlie to confront Hank, setting in motion an unpredictable chain of events.
As they plan to leave Whitey behind and press on, Dickie makes his entrance, determined to tidy up loose ends. This prompts Charlie to launch into a heart-pounding rescue effort alongside Hank. However, as they pursue Dickie onto a treacherously narrow bridge, Hank’s moment of hesitation proves to be a significant blunder, forcing Charlie to finally confront and dispel his insecurities.
In a dramatic culmination, Dickie meets his end at the hands of Whitey, who uses a well-thrown lawn dart to dispatch him. With the aftermath of the confrontation leaving them soaked as they tumble into the river below, Charlie’s sons, having commandeered a police helicopter, swoop in to save them. Reunited, they join forces with Whitey, who fesses up to his fabricated tales, a ploy to avert Hank’s scrutiny.
As law enforcement closes in, the corrupt officers Gerke and Boshane are apprehended, while Charlie emerges as a hero for aiding in the capture of the criminals. Irene's name is cleared, and they decide to embark on a fresh start together. In a heartwarming twist, Charlie proposes to Irene, who joyfully accepts.
In a whimsical post-credits scene, Whitey’s quest for Charlie's thumb in the river leads to an unexpected twist – it becomes a delightful snack for a lurking fish.
