Kate, Anders, and Eric pay a visit to Michigan's Upper Peninsula, where Kate's relatives, who work at a mansion, tell them about a lost treasure map hidden somewhere on the grounds. The appearance of two shady-looking men sets the stage for danger and excitement, as the kids try to get to the map before the they do.
