When Santa Claus lies dead and flattened (as if he'd fallen from his sleigh) in the middle of a shopping mall on Christmas Eve, Homicide Inspector Rebecca Mayfield is on the case. As she attempts to solve the homicide, a stranger shows up seeking help in tracking down a van full of Santas creating havoc throughout San Francisco. Rebecca is certain he has information that will help her case ... but she never expects he could also bring her some much-needed Christmas cheer.
