This is a film I saw incidentally about two years ago on the British “Horror Channel”.
IIRC Darren McGavin played the role of a psychiatrist whose patient tells him about her abduction during a hypnosis session. At first he`s sceptical, but in the course of the film his opinion changes to a degree where he shocks his colleagues by saying the abduction phenomenon is real.
From the looks of it, this film was produced during the 70s or early 80s.
Thanks in advance for your help!
