It's the beginning of December in Rudolph, New York, America's Christmas Town, and business is brisk at Mrs. Claus's Treasures, a gift and decor shop owned by Merry Wilkinson. The local amateur dramatic society is intensely preparing a special musical production of A Christmas Carol. But it's not a happy set, as rivalries between cast and crew threaten the production. Tensions come to a head when a member of the group is found dead shortly after a shopping excursion to Mrs. Claus's Treasures. Was someone looking to cut out the competition? Everyone in the cast and crew is a potential suspect, including Aline, Merry's mother, and Merry's shop assistant Jackie O'Reilly, who was desperate for a starring role. It could be curtains for Christmas - and for Merry - unless the killer can be ferreted out of the wings.
