Production
The film was based on a script by Ray Dennis Steckler called Warning - No Trespassing. Ted Newsom was hired to rewrite by Hal Freeman, who had made a lot of money making pornographic films and wanted to expand into other genres. Newsom made the script a cross between Ten Little Indians and Friday the 13th. He says Freeman financed the film entirely himself.
Newsom wrote the film to be shot half on location and half in a studio but it ended up being shot entirely on location over two weeks. The film unit was based out of Barstow in California.
Release and canceled sequel
The film was released on video.
Newsom wrote a follow-up for Freeman called Judgment Night about a convicted murderer who escapes prison and seeks revenge. Freeman died before it was made.
