Eighty-six-year-old Irving Zisman is grieving the recent death of his beloved wife, Ellie, but his grief is surprisingly complicated by a profound sense of liberation. His newfound freedom is abruptly interrupted when his
estranged daughter, Kimmie, is sent back to prison for drug possession, leaving behind her eight-year-old son, Billy. Kimmie has one demand before she goes away: Irving must take the boy across the country and deliver him to his deadbeat, good-for-nothing father. Reluctantly, Irving accepts the mission, loading up his classic 1967 Lincoln Continental with his young grandson and embarking on a chaotic, cross-country road trip that serves as the backbone of their developing bond.Throughout the journey, Irving’s primary motivation is to quickly unload the child and return to his single, wild lifestyle. However, as the miles roll by, a genuine affection begins to blossom between the crude, aging
misanthrope and the surprisingly adaptable youngster. Irving introduces Billy to the unorthodox realities of the real world through a series of outrageous, jaw-dropping situations. They infiltrate a children’s beauty pageant where Irving dresses Billy in a full drag ensemble, complete with heavy makeup and a provocative dance routine, shocking the conservative audience. They crash weddings, disrupt funerals, and visit strip clubs, all while testing the patience, sensibilities, and moral boundaries of unsuspecting everyday citizens who capture the hidden-camera chaos with genuine reactions of horror and amusement.Despite the constant parade of bizarre and inappropriate antics, a tender emotional core anchors the narrative. Irving gradually realizes that Billy needs stability and real care, far more than what his irresponsible father could ever provide. When they finally reach the deadbeat father's residence, Irving confronts a harsh reality: the man is completely unfit and utterly uninterested in raising a child. Motivated by a fiercely protective grandfatherly instinct, Irving abandons the original plan. He makes the life-altering decision to step up and officially become Billy’s primary guardian, embracing the responsibilities of late-life fatherhood. The film concludes with the duo happily hitting the road once again, not as reluctant traveling companions running an errand, but as a devoted, unconventional family ready to face whatever hilarious trouble comes their way next.
