When Holly White's fiancé cancels their Christmas Eve wedding with less than two weeks to go, Holly heads home with a broken heart. Lucky for her, home in historic Mistletoe, Maine is magical during Christmastime - exactly what the doctor prescribed. Except her plan to drown her troubles in peppermints and snickerdoodles is upended when local grouch and president of the Mistletoe Historical Society, Margaret Fenwick, is bludgeoned and left in the sleigh display at Reindeer Games, Holly's family tree farm.

When the murder weapon is revealed as one of the wooden stakes used to identify trees on the farm, Sheriff Evan Grey turns to Holly's father, Bud, and the Reindeer Games staff. And it doesn't help that Bud and the reindeer keeper were each seen arguing with Margaret just before her death. But Holly knows her father and is determined to exonerate him.

The jingle bells are ringing, the clock is ticking, and if Holly doesn't watch out, she'll end up on Santa's naughty list.
