Christmas in Hawaii is all surfing Santa Claus, palm trees strung up with lights and… murder? It's the most wonderful time of the year on Maui, although not so much for one of Zoe's patients. Zoe is convinced the woman was murdered, despite her death being ruled accidental, but the police won't listen to her so she goes to Charlie for help. The two of them, along with Dot and Rosie, set out to get justice for Zoe's patient. But what initially looks like it might be a simple case quickly becomes complicated, and Charlie finds herself in more danger than cookies left out on Christmas Eve. Oh, and is that Jake standing under the mistletoe? All Charlie wants for Christmas is to catch a murderer. That's not too much for a girl to ask for, is it?
