This time the trio is in historic Barkerville, a gold rush town with a secret.
Rusty, Katie and Sheila are sent out of town with Rusty's grandparents to keep them out of trouble. After witnessing what they take to be a ghost in the night, the three friends find themselves involved in a mystery from the past that seems to have a few other people interested as well. New information has come to light about a fortune in missing gold, a centuries-old curse and a missing miner. While the three budding detectives try and figure out which of the aging prospectors they keep running into is actually a ghost, they find they are in a race against time to recover the gold and return it to its rightful owners to avert a tragedy. Will they find the gold in time? Or will they suffer the fate of Three Finger Evans, the missing miner?
