Christmas Chronicl

In Lowell, Massachusetts, widow Claire Pierce struggles to keep her family together around Christmas following the death of her husband Doug, a firefighter who died on the job. Their son Teddy has lost much of his Christmas spirit, while their younger daughter Kate keeps it alive and believes in Santa Claus. On Christmas Eve, Claire is called in to work, leaving Teddy in charge. While watching old family Christmas videos, Kate notices an arm appear out of the fireplace, and deduces that it was Santa. Teddy agrees to help her prove it, on condition that she gives him the video she recorded of him stealing a car earlier that day. They set up a tripwire and hidden camera, and fall asleep in the living room. After Kate awakens and sees Santa, she and Teddy follow him on to his sleigh to get a closer look. Santa rides off with the kids in tow, but he and the reindeer are startled when Kate makes her presence known. In the commotion, he loses control of the sleigh, causing it to teleport and crash in Chicago, Illinois. After coming to in Chicago, Santa introduces himself and tells the kids he has to locate his reindeer, hat, and bag of presents, which were lost in the crash, in order to resume deliveries and prevent Christmas spirit from declining. They offer to help him to avoid being permanently on the naughty list.
