Sleepwalker

Saxon Logan directs this 1980s British horror. When a rich couple (Nikolas Grace and Joanna David) journey to the home of brother and sister Alex and Marion Britain (Bill Douglas and Heather Page) for dinner, they end up clashing with their hosts over their contrasting social and moral views.

A destructive storm ruins their dinner plans so instead they go out to a restaurant where they meet the establishment's strange owner (Fulton MacKay) and his employee (Michael Medwin).

As the foursome continue to argue over their differences, the tension builds and the night takes a blood-spattered turn for the worst.
