Plot summary
Shawn and Gus are hired by a childhood friend named Jason Cunningham ( MacKenzie Astin ) to find a missing camp counselor who disappeared near their old sleep-away campgrounds, Camp Tikihama. Suddenly, Gus and Shawn find themselves entangled in a web of murder mystery when they are all stalked by a psychotic killer. Shawn then discovers they have been invited there by Jason as "test subjects" because he is reopening the camp as a horror camp, a place where people pay to have themselves chased by a "killer." After Jason reveals the truth behind the incident, everyone present finds themselves with the roads closed, and trapped.
This time, at the mercy of a real killer. When people begin winding up dead, Shawn, Gus, and O'Hara try to find out who the killer is before it is too late. Meanwhile, Lassiter has dinner with his estranged wife Victoria ( Justine Bateman ), but it's a meeting he would rather forget.
