The Outer Limits (1995) - Season 7 Episode 3 -

A couple flee a present-day religious community they've joined but find it's entirely surrounded by an invisible wall. They're the parents of the totally isolated cult's first child, who has a mysterious scar from a ceremony by the cult leader, who they caught sneaking off into the forest and teleporting into thin air. They're spotted by another malcontent, who's been searching for a way out for months. With nowhere to go and everyone else entranced by the idyllic new life, what can they do?
