Summerfield (1977)

Beyond the bridge was Summerfield. And a secret that should not have been shared.

When teacher Simon arrives in a small, secluded village to take over the local school, he is surprised to discover that his predecessor has disappeared without a trace - and that nobody seems too concerned about it. As Simon probes deeper into the disappearance, the inhabitants of a forbidding estate called "Summerfield" take on more and more significance.
