In this cheap knock off of John Carpenter's The Fog directed by Wisconsin 'B' movie wizard Bill Rebane (The Giant Spider Invasion), vengeful colonial ghosts led by the spirit of an executed warlock who resides in an antique piano return to wreak havoc on a small town during its bicentennial celebrations. The whole movie feels like bad community theatre production with poor sets and costumes sourced from a fancy dress supplier. There's some gore including a decapitation but it's all really poorly executed and you won't really care. The director served as associate producer on Ulli Lommel's much better The Devonsville Terror.
