8.00 26 minutes Zoe's father Graham grew up in the Valley. His grandparents were some of the area's first residents. While Zoe knows a lot about her family, one mystery remains: there is a tiny valley where her father used to go that he never talks about. In fact he's never revealed its location. Harvey figures out where the valley must be and he, Zoe and Lassie hike in to discover the truth about the spot.
