The infamous, Most Wanted Goosebumps characters are out on the loose and after you. For the first time ever, it's a Goosebumps Christmas! Kate Welles just wants the lead role in her school's Christmas play. Her annoying "friend" Courtney is constantly getting in the way of that. But Kate has to get along with her or else neither of them will be allowed to take part in the production of The 12 Screams of Christmas. Even worse, Kate and Courtney's teacher decides they need to find a special place to rehearse. A certain house with a lot of history. The kind of place that Kate would normally be pretty frightened to go into. The kind of place that gives new meaning to the term "Christmas Spirit."
