Mrs. Claus and the Nightmare Before New Year's

April Claus is looking forward to relaxing with her hubby, Nick (aka THE Santa Claus), in the week between Christmas and New Year's Eve. But just after Santa departs for his deliveries, an elf pulls into Santaland with three people he found lost in the frozen wilderness. The survivors of a scientific expedition are injured, but their presence endangers the future of Santaland. So, while the strangers recuperate at the infirmary, April convinces Christmastown to pull off its grandest, most impossible, most magical feat yet... pretend to be normal!
