When a family come into possession of a statue called The Grinnygog, a trio of benevolent witches are summoned to the village where they live.

An ancient church is being dismantled and moved to a new location, stone by stone. One of the gargoyles from the stones falls into the possession of a mother who takes the stone man back to her family. Soon after, four strangers show up in the village and the Sogood & Firkettle children seem to be the only ones who question the mysterious things that begin to happen. This film was originally broadcast across six 25 minute episodes with a total runtime of 150 minutes. A few years later, the US cable network Nickelodeon edited the miniseries into a 2 hour (including commercials) movie block. This 2 hour edited version was shown throughout the 1980s on US television.
