Newlyweds Dale and Brenda Hargrowe return to Massachusetts from Oak Ridge, Tennessee, at the end of WWII to begin their married life together.
What they don't know is that in Salem, there is a group of followers of a young girl whose cousin was one of the people hanged during the infamous witch trials of 1692. This group thinks this girl was a prophetess because she had visions of future events. One such event was of a female descendant of the presiding clergy at one of the hangings. This woman would someday come to Salem to face retribution for the part her ancestor played in the hanging of many innocent people.
They think Brenda is the fulfillment of that prophecy!
Also, one of Dale's college professor colleagues puts him "on notice" that there are real witches in Salem, and they want their revenge on Christians for what took place in 1692.
These two groups begin a two-pronged attack on Dale and Brenda in their desire to get revenge on anyone who believes in the one true God whom they so demonically hate.
Together, Dale and Brenda fight the forces of wickedness in a place where wickedness has lived for centuries--Salem!
