It's Christmastime in turn-of-the-century Toronto, and Detective William Murdoch (Yannick Bisson) and his team have a murder to solve. At a charity gala for sick children, Murdoch and Dr. Ogden (Helene Joy, "Durham County") find the host, dressed as Santa Claus, dead from a broken neck. To make matters worse, all the presents that were collected for the children have been stolen. When witnesses report hearing a wild animal near the scene, Inspector Brackenreid (Thomas Craig, "Coronation Street") suspects the legendary creature Krampus. Meanwhile, Constable Crabtree (Jonny Harris, "Still Standing") worries he'll have nowhere to spend the holidays. Can Murdoch and the rest of Station House No. 4 catch the murderer in time to save Christmas? Brendan Coyle ("Downton Abbey"), Kelly Rowan ("The O.C."), and Ed Asner ("The Mary Tyler Moore Show," "Up") guest star in this feature-length Christmas special.
