An act of benevolence towards a stranger leads to terror and betrayal in this psychological thriller. A young couple is vacationing in the Catskill Mountains when they pick up a hitchhiker; the man seems well mannered enough, and they eventually buy him dinner and let him stay in their motel room. But they quickly learn that hes not nearly as benign as his initial appearance suggests, and they soon find their lives in grave danger. Kaaterskill Falls was shot on a shoestring budget, with directors Josh Apter and Peter Olsen comprising the entire production crew; the dialogue was all improvised by the actors (Hilary Howard, Mitchell Riggs, and Anthony Leslie), while guitarist Steve Tibbets contributed the musical score. ~ Mark Deming, All Movie Guide
