After the tragic loss of his sister Janet and her husband, Michael "Mike" Maxwell finds himself unexpectedly uprooted from his role in Chicago. In a twist of fate, he takes on the onerous task of caring for his lively nephews—Justice, Junior, Samuel, and Simon Kicklighter—as social worker Gretchen Rice is on a quest to find a suitable foster home for them in the picturesque countryside of Ohio. These spirited boys are not only unruly but also homeschooled, dabbling in various adventurous (and sometimes risky) recreational activities on their family farm.
As Mike juggles his new responsibilities, he faces pressures from his advisor, Carol, who threatens to reassign the project to Devin, a newcomer with no experience that Mike firmly dislikes. Complicating matters further, Mike is also tasked with closing a Realtor deal for a train yard while managing his unexpected role as a guardian.
As the days unfold, Mike gradually starts adapting to the rural lifestyle and learns how to engage with his nephews, drawing connections that hark back to their mother Janet, who had enlisted them in ballet at her local dance studio. His heart is set on keeping the two younger Kicklighters despite attractive offers from potential foster families. Meanwhile, he orchestrates an invitation to the luxurious estate of well-to-do socialite Al Wilmington for a Christmas celebration, a chance that significantly impacts the children's chances of finding a permanent home.
At the party, Mia, a girl who attended the dance studio alongside Justice, emerges as Justice's dance partner. Initially, Mike mingles effortlessly and forges connections, yet chaos engulfs the night when the boys recklessly crash a golf cart into the nativity display, resulting in a comedic misadventure that results in chaos and a submerged cart in Al's pool—a result that dwells on whether or not Al will consider fostering them.
Additionally, amid his growing feelings for a woman named Rose, it is revealed she has ulterior motives regarding Mike's financial status, leading to a painful betrayal. Carol becomes appalled by Mike's actions and backtracks into Devin's safe hands, forcing Mike into a position where he must continue his search for good foster homes for his nephews.
Motivated by Junior's captivating rendition of The Nutcracker ballet, Mike sets out to stage a neighborhood theater production, viewing this as a potential means of creating funding and elevating the children’s chances at being adopted. With the encouragement of Mia, Mike manages to entice Justice into joining the performance alongside his siblings. However, during the performance, Gretchen inadvertently highlights Mike's growing attachment to his nephews, notwithstanding Mike's attempts to downplay those feelings, referring to them somewhat dismissively as a "pain in the ass."
In a twist of events preceding the performance, the kids mysteriously disappear just as Carol provides Mike with an urgent call for assistance. Out of the blue, Mike is left to announce that the play will be canceled; however, he soon discovers that the Kicklighter children have taken it upon themselves to honor their parents with an outdoor performance, much to the delight of the spectators around them.
As the drama unfolds, comedic interactions ensue, including an amusing moment where Justice brandishes his prop sword to 'injure' Mike, who humorously pretends to be wounded. Ultimately, Mike experiences an epiphany, realizing the depth of his affection for his nephews and pledging his lifelong commitment to their well-being. The streets become alive with joyous celebration as the performance concludes. In a humorous nod, the credits reveal Mike has acquired Justice an ATV, a twist that promises more shenanigans, as it showcases Mike and Justice failing spectacularly at a jump, leaving the audience with a hearty chuckle as the sound echoes during the closing scenes.
