In this continuation of the Ma and Pa Kettle adventures, the endearing rural couple, Ma Kettle, [Marjorie Main], and Pa Kettle, [Percy Kilbride], receive a telegram announcing that Pa has won another jingle-writing contest, this time from Bubble-Ola. The prize promises an all-expenses-paid trip to New York City, a glimmer of big-city excitement that Ma worries they cannot fully enjoy because they have no one to look after their lively brood of kids. Yet fate takes a sharp turn when a fleeing bank robber named Shotgun Munger, who has a flat tire, careens into the old Kettle Farm. Munger, desperate to evade the law, persuades Pa that he is an eccentric poet named “Mr. Jones” and asks Pa to stay behind to watch over the kids while he disappears into the crowd. In exchange for this cover, Pa agrees to deliver a bag to his supposed “brother” Louie in New York, a plan that will pull the Kettles deeper into a web of misdirection and suspicion.
Before long, Ma and Pa board a train to join their son Tom Kettle, [Richard Long], and daughter-in-law Kim Parker Kettle, [Meg Randall], who are living in New York City as Tom tries to finance a chicken incubator project. Tom’s world is a mix of ambition and family chaos, and Kim’s presence keeps the family grounded amid New York’s hustle. The bag Pa promised to bring, containing $100,000 from the very bank robbery Munger is fleeing, is missing when they check into the Waldorf Astoria Hotel. The distraction at the busy station has allowed the bag to be stolen, and Pa must scramble to compensate for the loss as he navigates a city that suddenly seems full of potential crooks.
In a series of quick, comic twists, Pa purchases several new bags to give to his mysterious contact Louie, only to see each empty bag spirited away by Louie’s confederates who have begun to suspect that Pa himself might be part of the theft. The chase for the missing cash becomes a source of mounting confusion, and Pa’s attempts to stay one step ahead only escalate the entanglement. Eventually, Pa agrees to meet Louie by the Central Park Zoo’s famous monkey cage, hoping the exchange will finally settle the matter. That plan nearly derails when Pa is mistaken by the police for a monkey-poisoner at the zoo and is arrested, a misunderstanding that seems almost crafted for a farce but is rooted in the day’s chaos.
Tom steps in to help, using his own wits to convince the police of his father’s innocence and to untangle the tangled thread of the bags and the elusive “Mr. Jones.” The case leads them to a wealthy investor, whose party becomes the scene of a crucial breakthrough: the missing bag is found in the investor’s luggage, and the police are able to round up the entire gang with the cash as essential evidence. The investor, recognizing the Kettles’ ingenuity and spirit, signs a deal with Tom to finance his chicken-incubator invention, a moment that promises new opportunities for Tom and his family.
Returning home, the Kettles discover that the beleaguered “Jones” figure has endured a farcical, chaotic reception at their house: he is overwhelmed by fourteen energetic Kettle children, hogtied in a game of cops and robbers, and then handed over to police who rush to “protect” them all. The mix of chaos, teamwork, and lighthearted perseverance underscores the enduring bond of the family. Through a series of misadventures, misdirections, and heartfelt moments, the Kettles manage to outwit trouble, secure a future for Tom’s invention, and reclaim their ordinary life, albeit with another round of memories that will be recounted for years to come.
