A billion-dollar oil company led by Sumner Murdock [Mason Adams] launches a high-stakes Arctic exploration that is greenlit and overseen by Michael Baldwin [Paul Le Mat]. The plan centers on blasting through ice to reach potential reserves, but the first attempt at Site A yields no oil. The Baldwins’ home life becomes tense: Claudia Baldwin [Jaclyn Smith] longs to move their family back to Los Angeles for a seemingly more civilized life, while Michael clings to the project because it was his idea. Their three children—Marianne [Laura Jacoby], David [Scott Grimes], and C.B. [R.J. Williams]—argue about the existence of Santa Claus, adding a festive glare to the mounting pressures of work, money, and a looming career payoff. Against this backdrop, Murdock’s corporate impatience grows louder, threatening to cut Michael loose if the expedition doesn’t deliver.
The following day, Michael returns to the office where he is confronted by Santa Claus’s chief elf, Ed [Paul Williams]. Ed explains that their dynamiting is damaging North Pole City, the home of Santa and his elves, and that blasting at Site B could devastate the magical city due to its proximity. At first, Michael assumes Ed is pulling his leg and laughs it off. The next morning, Ed arrives in a modified World War II snowcat and proposes taking the Baldwins to North Pole City to demonstrate that Santa is real and to reveal the harm their actions are causing. Claudia and the kids, still seeing it as a prank, reluctantly agree to go along.
In North Pole City they meet Santa Claus [Art Carney] and Mrs. Claus [June Lockhart]. Santa unveils some astonishing secrets: a device that slows time so he can complete all his deliveries in one night, and anti-radar tools that shield North Pole City from detection. He shows how Site A’s blasts have already taken a toll on the city and warns that a blast at Site B would spell the end of Christmas as they know it. He also hints that the main oil field lies at Site A, prompting Claudia to question whether she’s really seeing what she’s been told. Santa’s magical memory proves his truth when he recounts a Christmas moment from Claudia’s own childhood that only Santa could have known, shifting her skepticism toward belief.
Back home, Claudia relays Santa’s warning and the supposed location of the oil to Michael and Sumner Murdock. Murdock suspects foul play—perhaps a hallucinogenic manipulation—by Gaylord, a rival oil magnate mentioned in the press, and presses to finish Site B’s blast on Christmas Eve to beat the rivals to the oil. The family’s newfound belief tightens into resolve as the kids secretly plan to warn Santa. The youngest, C.B., stays behind to tell Claudia where the others have gone. Claudia, determined to intervene, climbs into her plane and tracks the clues through an ominous ice fog. Santa answers the call, taking the family aboard his sleigh and guiding them back to North Pole City, where the fog traps Claudia and the children inside until it lifts.
Meanwhile, Michael remains fixated on Site A, continuing to dynamite there despite orders to postpone. The countdown at Site B intensifies as Christmas Eve approaches. A crucial breakthrough comes when C.B. learns from a crew member that a gigantic oil field has been found on Site A. He rushes to tell his father, who races to halt the process. Michael radios the man in the hut near Site B and implores him to stop the countdown. The worker evades the detonation just in time, pulling the plug on the blast.
That night, Santa quietly returns Claudia and the children to their home as he continues his own deliveries. Murdock arrives, eager to press Michael about the decision to continue with Site B. Michael reveals that oil has indeed been found at Site A, ending the suspicions about the other site. The family steps onto the porch to witness Santa’s signature exit—the reindeer-drawn sleigh crossing the night sky. The moment softens Murdock’s hard edge, and he offers Michael a promotion, though Michael declines. His priority is to keep Claudia and the kids happy, choosing to move the family back to Los Angeles where they can rebuild their life together.
In the end, the story resolves with a return to family first, a Christmas miracle grounded in reality, and a business reversal that aligns ambition with the well-being of those who matter most. The quiet magic of Santa’s world reconciles a stubborn executive with the true value of home, leaving the Baldwins ready to pursue a future where work and love can coexist, and where the spirit of Christmas endures beyond the profit-driven glare of corporate pressure.
