Silver bells ring out, but in the air there's a feeling of...murder.

Pine Bluff, Oregon resembles a perfect cozy Christmas card. Sparkling Christmas trees line snowy main street. Wreaths, red ribbons, and colored lights adorn every door. Hardware store owner Dawna Carpenter is in a festive mood. She invites her elderly neighbor, Smitty, to join her and daughter April on the Christmas Light Tour, a trolley that takes guests through all the best decorated neighborhoods while they enjoy steaming mugs of hot cocoa and scrumptious treats.

But when Smitty spies one of the homeowners dead—a macabre decoration in an otherwise merry display—the cheerful ride turns somber fast. Dawna notices the ghost of the deceased woman standing next to the display, clearly angry over her recent demise. As snow blankets the valley and her newest employee is implicated in the crime, it's up to Dawna to find out who's been naughty and who's been nice—before it's lights out for her, too.
