"What's going on at the art museum in Pleasant Valley? Did the Egyptian mummy really come to life after three thousand years? The terrified night watchman claims that he saw the mummy walking around the museum. The very same night, the most valuable painting was cut out of its frame. Young detectives Jerry and Maya are on the case and determined to get to the bottom of the strange and spooky events."
