The Hidden Valley

Stacey and her best friend, country-wise Alexis, set out on a horse-packing trip. Journeying through the Chilcotin mountains besieged by storms, Stacey's horse goes missing. The clues lead them through a cavern which opens into a hidden valley full of prehistoric flora and fauna. The mystery deepens when they are taken captive by a group of indigenous people living a paleolithic lifestyle that has remained unchanged for centuries.
