The cops find vacation in a holiday resort. Piecing the clues together, the detectives learn that a group of devil worshippers have kidnapped two little girls who are to be killed...
Starsky and Hutch retreat to the mountains to get some peace and quiet but they end up encountering Satan's Witches.
On arrival at the peaceful resort, they are confronted by angry and suspicious residents. And their cabin, situated by the side of a scenic lake, is close to a group of weird-looking devil worshippers.
Starsky and Hutch begin to get rather annoyed when their privacy is disturbed — like a sign on their door in blood, a deadly snake in the cabin and a dead dog.
Obviously, someone is trying to scare them away — except that these stubborn cops aren't so easily frightened.
While doing their own investigations, they discover so me puzzling things. The sheriff is as hostile as the inhabitants. And they all seem to be scared of something.
When they try to probe further, they are thrown into jail for no apparent reason...
