Most horror movies begin with a black screen reading "Based on a True Story," and while many of them are, it isn't often that the story behind the plot is more horrifying than the film itself. This, however, is one of those cases. The movie 'The Strangers' is a nightmare-inducing project that follows a young couple as they fight for their lives in a remote home, stalked by masked murderers who make every moment bone-chillingly terrifying. It's inspiration, the Keddie Cabin murders, is a story that is somehow even more horrifying, just as scary as it is tragic. On April 11th of 1981, a mother and her three children were viciously attacked in their home in the Keddie Resort in California. Three of them would be found murdered, while one of the children would remain a missing person until years after that horrific night. The identity of their killer remains a mystery to this day.
