Colleen Stan is a nineteen-year-old hitchhiker in Red Bluff, California, when Cameron Hooker and his wife Janice offer her a ride in 1977 and never let her go. For nearly seven years Hooker keeps her locked in a coffin-sized wooden box under his bed, some days for up to 23 hours, forcing her to sign a so-called slave contract and calling himself her master. The film lays out the mechanics of that captivity: the box's exact dimensions, the sexual abuse and psychological conditioning Hooker used to keep Stan compliant even during stretches when she was allowed outside, and Janice Hooker's role in the arrangement before she eventually goes to police. Investigators and those close to the case describe how the abuse stayed hidden in a small town for years and how the prosecution came together once Janice talked. Stan's decision to rebuild a public life afterward, writing about the ordeal and speaking publicly, closes out a case built on control sustained in plain sight.
