The ghost of a witch returns to her place of residence before she died, a rural farm, and possesses one of the current occupants.

Trivia:
The series was brainchild of the Hammer Films producer Roy Skeggs, who had taken over the studio after it had gone into receivership the previous year, this was a marked change for the brand as their theatrical releases had been going downhill throughout the 1970’s due to their inability to stay up to speed with modern horror tropes.
