Emily Erickson (Judy Parfitt) is an academic and psychologist who has aroused the interest of Dr Pickering (John Neville.) He wants her to take part in some research regarding ESP.
Her husband is concerned about this but Emily goes ahead to meet Dr Pickering. He turns up on the train she is travelling in and then whisks her away to an isolated house. Not the the place she was meant to go.
Emily should be worried. Dr Pickering has hired a psychiatric nurse Dawson (Victor Maddern) telling him that she might be a difficult patient.
When Emily arrives, Dr Pickering explains his hypotheses. That the dead can communicate and he plans to experiment regarding this.
The test subject will be Emily and she is locked in her bedroom for days. Her husband is worried as Dr Pickering has made a contraption where Emily will be drowned and the last image she will see will be that of Dr Pickering.
Emily's only hope has to be Dawson, maybe he will realise that Dr Pickering is a crank.
There is a fantastically unhinged performance from John Neville. It is let down by flat direction which robs it off thrills. Emily becomes a passive character relying on others to come to her assistance.
It is strange that no one in the village or Dawson come to realise that Dr Pickering is not all there.
