This is an interesting program.

Set in the early 1900's, a Bostonian and his wife visit a country cottage in New Hampshire some months after he experienced a bout of influenza that nearly killed him.

It is intended as a rest period for him, but while there, he begins hiking treks around the local countryside.

On one of these hikes, he finds the ruins of an old church and for some reason circles it twice - counter-clockwise.

Apparently, this uncorks a disastrous series of events.
