A car drives up a country road and stops. The man driving the car looks up to see a country cottage and his expression becomes puzzled. He drives up to the cottage, where his host Elliot Foley (Roland Culver) greets him in the driveway. He is Walter Craig (Mervyn Johns), an architect whom Foley has invited to his country home in Kent to consult on some renovations. Upon admittance to the sitting room of the cottage, Craig reveals to Foley and his assembled guests that, despite never having met any of them, he has seen them all in a recurring dream.
