Talk about the winter blahs. Sam: Dog Detective can't find a mystery anywhere. The sheepdog sleuth doesn't know how she's going to make it through another snowy season. But things begin to heat up when her friends, Jennie and Beth, visit a museum. There they see the mummy of a pharaoh who is said to walk the earth searching for his beloved missing dog. Now Sam -- who always feels she deserves the royal treatment -- has the mummy hot on her trail. Will she be able to elude this creepy corpse as he stalks Woodford looking for his shaggy white dog?
