When her best friend's dad is falsely accused of stealing the town's prized jingle bells, a young amateur sleuth and her friends must find the real thief before Christmas.

One-hundred years ago, a strip of Santa's magical jingle bells were discovered by a young boy in Pleasant Bay, Oregon, bringing about a century of prosperity and peace for the small town. Now, just days before Christmas, the bells - the lifeblood of the town - are missing, and it's up to a group of intrepid kids to solve the case, find the bells and restore the Christmas magic to Pleasant Bay and its citizens.
