Synopsis by Janiss Garza
When his mother (Alice Taaffe) dies, Bryce Cardigan (Wallace Reid) and his lumberman father James (Charles Ogle) bury her in a glade they own and have named the Valley of the Giants. The two men swear to protect this land, but when Bryce returns from college he discovers that his father is in dire financial straits and is nearly blind. The old man's business rival (Ralph Lewis) intends to get his hands on the Valley. To complicate matters, Bryce is in love with Pennington's niece, Shirley Sumner (Grace Darmond). Through a lot of physical and mental exertion, Bryce exposes Pennington as a crook, saves the Valley, and gets the girl. This picture was based on the book by Peter B. Kyne. While shooting this film on location in California redwood country, Wallace Reid was seriously injured. He was prescribed narcotic painkillers to avoid shutting down production, and this reportedly lead to the drug addiction which eventually killed him in 1923.
