A witch is hung in England, but not before she curses her captor. Many years later a descendant of that captor now lives in the USA on a university campus. One of the students, Jill (Anitra Walsh) is obsessed with the occult after discovering an old book and performs a spell to summon a witch.
Unfortunately, the witch summoned is the one hung three hundred years before. Now the witch has possessed Jill and seeks revenge on her professor (Robert Elston) as well as terrorising the campus...
This is a low budget shock fest but looks great and is a lot of fun. The final battle is completely psychedelic and pretty wonderful to be honest. A perfectly decent early 1970s horror.
