The Fog (1980)

Antonio Bay, California has turned a hundred years old and getting ready to celebrate its centennial year. But as the residents of the small, quaint harbour town begin to prepare for the festivities a mysterious cloud of fog appears upon the shore and begins to make its way across town leaving a trail of horrifying slaughter until the deathly, dark secrets of Antonio Bays blood soaked history is finally revealed. The Fog is an incredibly atmospheric and effective ghost story that confirms John Carpenter as a master of terror.
