As the Saunders family settles into their new home in Edmonton, the festive joy seems to have eluded them — with the exception of six-year-old Mary, whose unmatched enthusiasm remains unwavering. With Christmas fast approaching, they venture to the magnificent West Edmonton Mall, hoping to rekindle some of that holiday spirit. Amidst the bustling throngs, 14-year-old Danny and 12-year-old Brian uncover a startling truth: their father, Wayne, has lost his job, burdening them with the grim reality of a Christmas devoid of presents or celebrations.
In light of her parents' gloom, Mary takes it upon herself to reach out to Santa Claus, expressing her heartfelt wish for a million dollars for Wayne — all while blissfully unaware of his recent job loss. Simultaneously, Brian cautions her about the fabled Mall Ghost, a mythical entity said to watch over wayward children who stray too far from their guardians.
While the Saunders family glides over the ice rink, they remain oblivious to the unfolding chaos. Leonard and Sheldon Cardoza, enveloped in a heated argument regarding their dubious scheme to distribute counterfeit currency, inadvertently send a bundle of fake bills tumbling onto the ice. Unaware of the true nature of this find, Brian and Mary mistake it for an early Christmas gift from Santa.
Emboldened by their newfound "wealth," they embark on an extravagant shopping spree that could rival even the savviest of shoppers. As news of the counterfeit cash spreads, Ginger Peachum bursts onto the scene, chastising Leonard and Sheldon for their reckless actions. Desperate to erase their traces, they dash after Brian and Mary, only to discover that the children have vanished into the maze-like corridors of the mall.
Meanwhile, Wayne grapples with the challenge of selecting the ideal gift for his wife, Judy, who is thousands of miles away in Los Angeles, facing a cascade of unexpected delays. As the authorities zero in on the counterfeit cash mystery, Detective Gordon McLoosh from the Royal Canadian Mounted Police (RCMP) steps in, determined to uncover the truth, mistakenly believing Wayne to be the mastermind behind this operation.
As the holiday festivities unfold, Brian and Mary revel in their newfound fortune, indulging in the spoils of their counterfeit cash acquisition. Conversely, Wayne's search for the perfect gift for Judy becomes increasingly fraught, exacerbated by his own confusion and anxiety. During this chaotic pursuit, Danny finds himself scouring Santa's Village for his siblings, only to face obstacles created by Leonard and Sheldon, hot on their trail. This pursuit leads them to an unexpected encounter with a girl from the water park, who invites them for a refreshing cup of Booster Juice. Their conversation reveals shared histories — both hailing from Los Angeles, united in their disdain for Edmonton — as they bond over sibling rivalries, weaving the fabric of fate closer together.
In Los Angeles, Judy's journey hits a snag at LAX Airport, where she encounters the enigmatic Kristopher Kringle. His prophetic words, "Things always work themselves out one way or another," unknowingly set into motion a series of events that will dramatically affect her holiday season.
As Wayne's night descends into chaos, he finds himself in the clutches of law enforcement, arrested by the fervent Detective Gordon, who is determined to make sense of the situation. Witnessing Wayne's arrest, Brian and Mary find themselves pursued by Leonard and Sheldon, who are relentless in their pursuit. Their paths intersect with Ginger once more, but quick-thinking Brian manages to evade capture yet again. Meanwhile, Wayne is entangled in bureaucratic complications, remaining unaware of the real severity of his predicament. It is only after the Saunders family is exonerated of all wrongdoing that Wayne learns the shocking truth: the money that caused all the turmoil was counterfeit, and his troubles are far from over.
As the night continues, Leonard and Sheldon find themselves at the mercy of mall security, ultimately leading them right into Detective Gordon's awaiting arms. This shocking revelation sends ripples of disbelief through the group, leaving everyone in a state of shock. Back at home, the Saunders family's holiday plans have ground to a halt, their hopes and preparations interrupted by the whirlwind of chaos that ensued. When Christmas morning finally arrives, Judy finds her way back home just in time to absorb the festive scene before her: a beautifully adorned tree, a mountain of presents, and a perfectly roasted turkey. It seems as though Santa worked his magic, but little does she realize that the true source of their holiday merriment lies in a far different realm...
